Why do we need the Semantic Web?

According to recent reports, the world sites on the Internet has more than 100 million, the Internet has become the largest building in human history database, which involves almost all the known areas. Internet use is now written in HTML page as a data carrier, which intertwined through a hyperlink, so people can easily access the data. HTML language is one of the technologies supporting the Internet, which the prosperity of the Internet has played an indelible role. Undeniably, HTML language has its inherent flaws - as a performance-oriented markup language, it only defines the tags used to format the data set, and the lack of clearly marking the meaning of data. This resulted in the HTML page, the data in the form of its blend together, the computer only to understand how to display a page, but it does not really "understand" the information on this page. Therefore, a number of Internet-based applications such as e-commerce, intelligent information retrieval, intelligent agents, has not really intelligent and automated. Internet researchers, has been trying to solve the problem. So far, the search engine technology is the most successful attempt. Search engine technology to natural language processing (Natural Language Processing, NLP) based in the related areas of the large amount of theoretical research and practical application, but still faces great difficulties, the information query precision and recall is difficult to further. Now the search engine, mostly through keyword search, to find the information you need, it would also bring a lot of interference from irrelevant information, we need to manually re-filter. For example, if you use the keyword "apple" and the search engine simply can not know that you are looking for a fruit, or looking for information about Apple, or Apple's brand jeans. Root of the problem is that "Apple" is the word on the computer does not have the "semantic."

Semantic Web is committed to change this situation, it is the focus of research is how the information that the computer can understand and deal with the forms, that is with a "semantic." The concept of the Semantic Web, "meaning" is the core, can be between man and computer, computer to computer without deviation between the way the message is semantic. The basic idea of the Semantic Web is the Internet any resources to conduct a structured descriptions and the introduction of semantics, so the computer can understand the information on the Internet. Of course, the computer can not really like people to think, but by setting standards, using the standard descriptions of the meaning, the computer can automatically according to the standard analysis and reasoning, will be integrated with network services, enabling automated intelligent services into possible.

Semantic Web is how it works?

In order to achieve the Semantic Web Intelligence and automated processing of information, goals, Semantic Web researchers have developed many new technologies and proposed a series of standards and norms. Widely recognized framework for the Semantic Web system by Tim Berners-Lee put forward, as shown in Figure 1, bottom-up a total of 7 layers.
W3C Semantic Stack Figure 1 Framework of the Semantic Web

Layer 1: URI and Unicode, the Semantic Web infrastructure.
Must first say a few words URI (Uniform Resource Identifier), the Chinese are usually referred to as "Uniform Resource Identifier", which is the foundation of the Semantic Web. Now identified with the use of the Internet URL, like HTML pages, Semantic Web also requires a similar specification, is used to uniquely identify the network resources. Semantic Web use URI specification, the specific specification in RFC 2396 for a detailed description. Any organizations and individuals are free to define and use the URI. Need to clarify a concept, URI and URL to use is very different. URL is used to identify a network path, can be accessed on the Internet at this URL to the corresponding resources; but the resource identified by a URI may be impossible to access to the network, it identifies and only identifies a resource, does not contain both The resources of the access path. Conceptually speaking, URI includes URL.
Surely you are not familiar with Unicode, it is a character set, the character set with all the characters are two bytes that can represent 65,356 characters, and basically includes all the world's languages characters. Semantic Web's ultimate goal is to build a global information network, it must cover all countries and all nationalities of the language, using Unicode as its character encoding scheme that can fundamentally solve the cross-regional, cross-language character encoding format standards.
This layer is the basis for the Semantic Web, URI for resource identification, Unicode encoding for resources.

Layer 2: XML, Namespaces, XML Schema and XML Query, Semantic Web syntax layer.
XML data representation and has become a de facto standard for data exchange, it provides a free format syntax, users can mark their own need to create the set, and write XML documents using these tags. Because anyone can freely define tag, so inevitably the situation will occur with the same name tag. W3C introducing Namespaces, which namespace mechanism, adding the tag URI index, and thus clears the conflict. For example, in which marked designation of the "cs" namespace to avoid conflict with other blog's tag. XML Schema provides an XML document on the mechanism for data validation. It is based on XML syntax, providing a variety of data types, the structure of the XML tags and use of standardized methods. XML XML Query is developed on the basis of technical standards, similar to XPath, etc. also use these techniques, data can be retrieved XML document, extract the node and other operations.
However, with XML in data exchange, application integration and other areas of popular, people gradually discovered, XML only describes the syntax of that data, but can not cover the semantics of the data. Given the general support of XML, the industry, and already has a more comprehensive technical standards, in the framework of the Semantic Web systems, as the syntax of data representation layer.

Layer 3: RDF Model, RDF Schema and RDF Syntax, Semantic Web data interoperability layer.
Not suitable for the expression of the semantics of XML data, therefore, the definition of the semantics of data and interoperability, which requires a higher level to complete. Therefore, W3C organization has developed a new language to describe Internet resources and their relationship, that is, resource description framework (Resource Description Framework, RDF). RDF uses triples to represent Internet resources, attributes and their values. In the Semantic Web concept, this is known as RDF triples the "statement (Statement)": subject, that is a resource (Resource), one of the property (Property) (verb) the value of an object (a resources, or the original value, such as the string).
RDF provides a standard set of data semantic specification, but it also need to define terms used in the description. RDF Schema (RDFS) provides a vocabulary for the computer to understand the definition of classes and properties provide the ability to describe. RDFS the RDF based on the introduction of the class, the relationship between class, property relations, and attributes such as domain and range. It is like a dictionary, the computer can understand by the meaning of the data. It has a significantly different from the object model, the property is independent of the class, an attribute can be applied to multiple classes or instances.
RDF Syntax constructed a complete set of syntax in order to facilitate automated computer analysis and processing. There are three common representations: graphic, N3, and XML. Among them, the graphical representation of the RDF model is a direct description of the model through the graphical RDF, RDF can understand the observed data and their relationships; N3 is a way to use triple by enumeration every RDF model "statement" to express the RDF model, it is the most easy to use, easy to understand; RDF / XML to RDF to describe XML grammar, the XML-parsing and interpretation process of integration, such, RDF parser to read XML in helping the same time, can get the XML to express the semantics and relationships according to their reasoning, and thus to make judgments based on semantics. However, RDF / XML is often because it is too complicated, difficult to use and be blamed.

Layer 4: Ontology, Semantic Web knowledge of the collection.
Ontology (Ontology) was first a philosophical concept, the scope of philosophy, the body is an objective explanation or description of a system, concerned about the abstract nature of objective reality. Artificial intelligence researchers first introduced to the computer field. On the body, one of the most popular definition is that "ontology is a shared conceptual model of the formal specification." This includes the meaning of 4 layers: conceptual model (conceptualization), clear (explicit), formal (formal) and sharing (share).
1) conceptual model (conceptualization): the objective world through abstract concepts in a number of phenomena which are the model, meaning that independent of their specific environmental conditions.
2) clear (explicit): the use of the concept and use of these concepts have a clear definition of the constraints.
3) formal (formal): Ontology is a computer-readable.
4) sharing (share): ontology is reflected in the common recognition of knowledge, and reflecting the related areas recognized set of concepts, it is aimed at groups rather than individuals consensus.
The goal of the extraction ontology domain knowledge, unified field of knowledge on a common understanding, identify areas of common recognition of the vocabulary, and from different levels of formal models of these terms and vocabulary given the interrelationship between clearly defined.
Semantic Web as the most core layer, ontology layer in the basic RDF and RDFS classes / attributes describing the basis of further describe the ontology and the relationships between them. This layer has its own specific ontology language. Historically there have been some impact, including, SHOE (Simple HTML Ontology Language), OIL (Ontology Inference Language), DAML (DARPA Agent Markup Language), and DAML + OIL. RDF is a simple ontology language, but its ability to describe the weak, the need for expansion. OWL (Web Ontology Language) is a W3C-recommended ontology language, it is more a reference implementation of the DAML + OIL design ideas and experience.

Level 5: Logic, rules and descriptions is the basis for automated reasoning.
Semantic Web is an important goal, is to realize automatic reasoning based on specific rules. This is a very complex task. Initially, around how to achieve this goal, or even whether we can achieve this goal, the researchers heated debate between. A typical topic is "RDF whether they have the ability to automatically reasoning?" Some people think that RDF / RDFS to quantify the lack of computing capacity.
For example, if your friend says, "" A Dry Story "is a good movie," You just read "A Story dry" and with his agreement. In this way, you will have a good friend of the judge to identify with. This recognition will certainly play a role in your reasoning. When he once again told us, "" The Promise "bored", you can based on the results between the judge on this comment.
Real life, people can make their own personal experience reasoning. In the Semantic Web, the researchers need to use this reasoning and quantitative methods to achieve that. In recent years, with the deepening of research, description logic (Description Logic, DL), as a more a more mature knowledge representation, to be entered into. OWL and other specifications of its designation, played a guiding role to some extent. Recently, researchers have begun to try to add rules in the formation of OWL OWL rules language ORL (OWL Rules Language), which can be better automated reasoning work.

6 layer: Proof, reasoning should be able to verify the results.
At present, the Trust for the Proof layer and the layer behind the research is not a lot, but a general consensus that, Proof and Trust within the field of the Semantic Web are two very important research topic. Proof Layer Logic layer using the definition of logical inference rules, draw some conclusions. For the Semantic Web users speaking, this reasoning should be based on reliable data based on the reasoning process should be open, and reasoning to the conclusion it should be verifiable.
Also use the example above, we reasoned that "" The Promise "is not a good movie." In real life, we can personally see "The Promise", and made judgments and conclusions on this reasoning to verify. In the Semantic Web, we must have such a verification mechanism. Computer concept, usually referred to as similar to the personal experience of "context." Context is made the basis of reasoning, therefore, the Semantic Web must establish a method of reasoning used to prove the accuracy and authenticity of context information.

Layer 7: Trust, Semantic Web should be a trusted network.
Reasoning within the Semantic Web and eventually come to the conclusion should be able to trust. This requires to satisfy two things: (1) can trust the data seen that context; (2) can trust the reasoning process. Meet these two before we can trust the final result by reasoning.
RDF model using the Semantic Web, anyone can describe any resources, the different positions of the people make the same resources may be the opposite of the description. Trust is responsible for the application layer to provide a mechanism to decide whether to trust the given proof. The establishment of Trust level, so that intelligent agents on the network to achieve personalized service, and automatic interaction between co-operation with the reliability and security.

Other: Signature, Digital Signature.
Hierarchical model of the digital signature in the right, runs through the middle of four semantic web. Digital signature is an Internet-based security authentication mechanisms. When information passes from one level to another level, you can use a digital signature description of information sources and security; this way, the receiver can identify its source by a digital signature and security, to determine the extent of information trusted. With digital signatures, a number of important e-commerce activities can be safely carried out in the semantic web. In fact, not only for the Semantic Web, the digital signature for all of the information exchange system are very important.

Network Summary

Now, the network ABSTRACT tools have become an important tool for Internet users who, I most often use is del.icio.us, feeling pretty good. Domestic and telecommunications networks Abstract 365key and is said to have done quite good, but I have not tried. I use del.icio.us on experience, the largest of its usefulness for me there are two points, the core of the collection and sharing.
1) record their daily reading, you can share with others, but also easy to stage their own conclusion.
2) through a common collection of users, find people with similar interests and their own.

I am not accustomed to using it to organize my bookmarks. I basically use the fixed line machine, use the browser's bookmarks, I only need to: (1) Open "Bookmarks" menu; (2) Click on the bookmark. But if you use del.icio.us, I need to: (1) First entry to my home page on it (sometimes even log); (2) and then select a particular tag; (3) and then click one of the collection, I can finally enter into the page. Clearly, the use del.icio.us I used a multi-step. As a frequently used function, your convenience is the number one, huh, huh.

My del.icio.us conclusion is that it is a collection / sharing of information a good tool, but not a management tool for knowledge. Of course, the people is designed to not have been used to manage knowledge, my conclusion is proof of the del.icio.us product design is successful.

But I need a tool for knowledge management. How can more effectively organize their own information, this is actually something worth pondering, especially for research people. I used to approach may be soil, but over time has also been used. Specifically as follows.

1, according to their interests, different categories of the establishment of a number of directories. Categories as detailed a number of points, so you can make directory hierarchy remain at the level of the directory hierarchy to avoid more complicated operation brought. I will only really interested in their own data collection, the temporary excitement of the thing, I will put a cool cool Temp directory, to be sure there is a need for a directory, I then copy them to the past. Facts have proved that a person can continue to maintain the attention of the classification number in fact very small. Continuing concern to go before we can sort out a number of contexts, found "really they are useful" things. Other occasionally exciting but something saved, when in fact the need to look at google or baidu, can be found quickly.

2, inside a directory for each file, I will write an index. I will give each file number, and simply write a description, such as "Help to build a recommendation system, the key technologies available." In addition, natural and ultimately, to extract keywords, papers to write more, have been more handy summary of the keyword. File description must be short, but said the most important benefit skim the surface of the visit; have too many keywords, helps to retrieve. Thus, the need to find information, I quickly had my description text can also search for keywords. google and baidu just launched the desktop search tool, I was very excited that you can use it to facilitate retrieval of relevant information. But after the trial had, I feel more disappointed. I need a feature, I selected a directory for indexing and retrieval, they do not. I do not need me to index the entire hard drive data, I simply do not have access, also in vain take up my hard drive space, my book is only 40G hard drive, high cost of land ah.

Of course, after all, earth way, other just fine, but he's the most inconvenient thing is: I have not found an effective way to keep track of the contents of these files - that is, knowledge - relationships. Aggregate keyword alone is not enough. Relationship similar to the paper I mentioned in the citation, I need to quickly locate a file in the quoted part, and not to link to this file on the matter. Of course, even the link to the file has not been resolved satisfactorily, even more directly targeted to the content to wish for.

Extended use of semantic web technology tools web Abstract should be one of the ways to achieve this goal. Implementation method and is now similar to the popular Tag, but the Tag is predefined. In order to be able to, and now Tag distinction below, I named this Tag Knowledge Tag, KTag. You can use the language like RDF to describe KTag, making it the expression of relations and have the ability to reason. Difficult to achieve initial surely there are two.

1, Standard KTag definition. Can refer to existing standards already have some, but not much. Also can start their slow accumulation, as now del.icio.us this way, when you add Tag, I suggest you the most common Tag, guide users to the gradual harmonization of the use of Tag. But no matter what method used, the background of the workload is considerable.

2, how to guide the user to correctly tag KTag. And now the biggest difference between Tag, KTag ultimately need to label the contents, but not only for the entire article. This provides the user with trouble, as I said more and browser favorites, like del.icio.us, ease of use is the determining factor, unless the Target User defined I do - and are willing to pay extra effort to knowledge for management effectiveness and efficiency. In short, the user experience is definitely a problem.

Practical experience in Chinese word segmentation algorithm

Recently as a search engine-related projects, not that that is clear is certainly developed based on Lucene, and standing on the shoulders of our predecessors ah, huh, huh! Familiar with Lucene know that, Lucene is not very good in Chinese word segmentation to achieve, I have done some of the features of Chinese word segmentation, initial test results were pretty good. Discussions around the Chinese word has a lot, but by the actual development, I do still have some of my experience, the intention to write this blog post, did not expect a sudden today, found that their partners have to write a paper, read a bit, feeling they want to say, he referred to, therefore, reproduced over.

The following is reproduced in the content, "The discussion about word"

---------------------------------------------

Full-text information retrieval system, inverted index created what word should be used when the method has been different opinions, there is no conclusion.

With my knowledge, there are certain paper "study that" the use of binary segmentation index is constructed through the "best"; also seen in the garden of a brother that the most accurate word segmentation (sorry, forgot specific source); of course, will be a dictionary or a total based on the current frequency of the Chinese word components packaged to join their project is also very popular practice.

Since there are so many views and practices, will inevitably make life out of a high commitment to the authenticity of the next or discernment;

However, as a mature and sensible young blood, even that this determination is not necessary because the information retrieval system evaluation criteria are diverse - recall, accuracy and efficiency of the three indicators contradict each other inquiries, only choice can not be reconciled; people are concerned about the indicators vary naturally present different views, pursue different approaches. Suppose you do a Web search engine, the first inquiry must be to ensure the efficiency, because it was dealing with huge amounts of data and concurrent request is a natural barrier; Second, the recall rate and accuracy rate in you will be more inclined to the latter, because the end user and the Web search engine, just as the negative relationship between the mind the relationship between man and woman infatuated - users want to be the most satisfactory results as soon as possible, and the next moment you abandon, until they need you up again (of course, if you provides the code for the Good Morni bid ranking service, in order to avoid customer complaints, better paying attention to the recall. So, the majority of white and a handful of VIP is a conflict of interest between the profound and long-term and irreconcilable. ..); same time, for a traditional library information retrieval systems, the situation will be different - the books and articles have a good keyword indexes, including title, author, summary, text, your time-defined structured data the document collection is relatively stable and relatively small - all to make your decisions more likely to improve the system of recall, the reason is very simple, you have the possibility to do or say is an advantage.

Now that we have clear indicators of evaluation of information retrieval system is diversified, and now let's look at the different sub-word indexing strategies in the end how they affect these indicators.

Let us first compare the two opposing strategies, words vs Chinese word segmentation:

Word segmentation of the strongest supporters of the evidence about the following:
"World Cup" is a word, with word segmentation, then check the "World" also hit this document, in Chinese word segmentation of finding a;
The Chinese word rebuttal supporters is about:
"Participated in the World Cup", with word segmentation, then search "death" of this document can also be hit, but in fact no one hangs up;

The above statement we can observe to be the case, with words cut branches to improve the system of recall rate, while the lower accuracy; the Chinese word is on the contrary, it increases accuracy, and reduce the recall rate, and word of The more coarse particles (average word length longer) this trend more apparent.

This conclusion seems to help to understand why google, Baidu, etc. The theory also requires high accuracy of Web search engines have adopted the Chinese word segmentation. But if our understanding remain at this level only appear a bit too much on superficial: the fact is that the high throughput required in dealing with the Chinese Web search engine, content must be in Chinese word segmentation.

Let us imagine an inverted index table, each row has a TermText and all documents that contain the TermText number list. In this way we check a particular keyword, you can one-time access to all documents that contain the keyword, rather than in one by one to find the original document collection. And use different strategies to create an index word, in fact, the document number is set to break up a different level to the index in different rows. Word segmentation can be described as a way to break up the lowest level, only the number of rows is equal to the number of Chinese characters, and the entire inverted index table will be very "wide"; the contrary, the coarser grain size of the Chinese word document number will be assigned to a collection of more many different lines, making the width of the inverted index table smaller. And as the word size of the increase in width will be decreased, the most extreme case is to document each one as a "word", then the width of the inverted index table is equal to 1 everywhere.

Based on the above discussion, we see that the following two points:
First, the number of very large document collections, the system throughput will be stored in inverted index file of the disk's performance limits, therefore, the use of Chinese word segmentation, to shorten the width of the inverted index table will help to improve the system throughput.
Second, regardless of Boolean queries, or location-based queries (such as Lucene in PhraseQuery) word segmentation of the word query performance is not better than the Chinese word.

It would appear that the use of the Web search engine is not a Chinese word difficult to understand what the; Similarly, smaller in the document, the use of word segmentation strategy would not be any major problems.

The binary segmentation, the dual view, this approach attempted in a rugged battlefield surgery to achieve moderation of ideological temperament, words and the Chinese word segmentation between the less than satisfactory in some respects a compromise (ambiguous, meaningless binary groups, etc.). It is closer in the realization of the word segmentation, rather than the Chinese word. According to Ou Di vision of achieving a kind of standard if the Chinese word meaning improvement strategy, it can be mitigated to some extent reduce the recall of Chinese word segmentation problem may be a more balanced in every solution .
