Semantically linked pages are queried based on a user supplied interest vector. The interest vector provides a weight for presenting results from the query of pages. The interest vectors are used to calculate the importance of pages of a query based on the weight of semantic links associated with the page known as page rank indicators. Optionally, the calculation is augmented by other page ranking algorithms. An indication of the resulting pages is displayed according to the calculated importance. Preferably the calculation utilizes a dot product of page rank and user interest vectors.

In the realm of managing relational databases, a system that uses both the data in a relational database and domain knowledge in ontologies to return semantically relevant results to a user's query. Broadly contemplated herein, in essence, is a system that bridges a semantic gap between queries users want to express and queries that can be answered by the database using domain knowledge contained in ontologies. In accordance with a preferred embodiment of the present invention, such a system extends relational databases with the ability to answer semantic queries that are represented in SPARQL, an emerging Semantic Web query language. Particularly, users may express their queries in SPARQL, based on a semantic model of the data, and they get back semantically relevant results. Also broadly contemplated herein is the definition of different categories of results that are semantically relevant to a user's query and an effective retrieval of such results.

A social network built around objects viewed over the Internet. A user interacts with a web page presenting a recognizable object (for example, a book, a restaurant or a stock quote). A plug-in in the user's browser extracts information from the web page, creates an identifier for the object, and records the interaction at a network node for the object and a network node for the user. The plug-in further creates a toolbar that is displayed with the web page, which identifies other viewers who recently viewed the object on the Internet and, in particular, other viewers who have been selected by the user as friends. The user may view a profile for any of the other viewers that provides links to the web page where the selected viewer viewed the object, to other objects viewed by that viewer and to other viewers linked to the viewer.

Semantic understanding of hypotheses returned by a speech engine could improve the quality of recognition and in cases of misrecognition speed the identification of errors and potential substitutions. Unfortunately, semantic recognition using natural language parsers is hard since semantic and syntactic rules for processing language are complex and computationally expensive. Additionally, semantic recognition should be performed in a knowledge domain—a domain of interest such as radiology, pathology, or tort law. This adds additional complexity to building semantic rules. The method described achieves semantic understanding by coupling a speech recognition engine to a semantic recognizer, which draws from a database of domain sentences derived from a document corpus, and a knowledge base created for these domain sentences. The method is able to identify in near real-time the best sentence hypotheses from the speech recognizer and its associated meanings, i.e. propositions, which belong to the knowledge domain, and if no hypotheses are found mark it as invalid for easy identification. For invalid sentences, closely matched sentences from the domain database can be displayed to speed correction. The semantic propositions can be semantically typed, such as normal and abnormal, further aiding in the identification of recognition errors. The system automatically displays the semantic meaning of related ideas of valid sentences by retrieving proposition (s) from the knowledge base.

The present invention relates to a system and method for intelligent ontology based knowledge search engine (IATOPIA KnowledgeSeeker). Said IATOPIA KnowledgeSeeker, is an intelligent ontology-based system that is designed to help Web users to find, retrieve, and analyze any Web information such as news articles from the Internet and then present the content in a semantic web. We present the benefits of using ontologies to analyze the semantics of Chinese text, and also the advantages of using a semantic web to organize information semantically. IATOPIA KnowledgeSeeker also demonstrates the advantages of using ontologies to identify topics. We use a Chinese document corpus to evaluate IATOPIA KnowledgeSeeker and the testing result was compared to other approaches. It was found that the accuracy of identifying the topics of Chinese web articles is over 87%. It demonstrated a fast processing speed of less than one second per article. It also organizes content flexibly and understands knowledge accurately, unlike traditional text classification systems used in popular search engines today such as Google and Yahoo.

A computer implemented method of constructing a computer implemented knowledge base, of evaluating a plurality of invoices, of knowledge refinement and generation, as well as a computer implemented knowledge base for analyzing a plurality of invoices. The methods comprise receiving the invoices, semantic and logically analyzing them to identify the invoice items (parameters and algorithms of service providers, billing plans, user profile, consumption pattern and debits) and relations connecting them and construct the knowledge base. The knowledge base comprises a hierarchic taxonomy of billing plans related to services of any domain (telecommunications services, banking, insurance, utilities etc.) and a computer implemented generic invoice constructed in reverse engineering logic for simulating debits. Debit simulations are done in order to achieve: 1. recommendations for optimal billing plans. 2. Recommendations for possible detected billing errors. 3. recommendations concerning new plans and/or services, and their financial implications Improving the knowledge base may use genetic algorithms based on an analogous hierarchic structure of the taxonomy to a genetic hierarchy, and may proceed by refining billing plans and comparing the resulting debits. Novel Semantic-web and Artificial Intelligence (AI) methods are used.

A semantic query over an RDF database is received with RDF database statistics and access methods for evaluating triple patterns in the query. The semantic query is expressed as a parse tree containing triple patterns and logical relationships among the triple patterns. The parse tree and access methods create a data flow graph containing a plurality of triple pattern and access method pair nodes connected by a plurality of edges, and an optimal flow tree through the data flow graph is determined such that costs are minimized and all triple patterns in the semantic query are contained in the optimal flow tree. A structure independent execution tree defining a sequence of evaluation through the optimal flow tree is created and is transformed into a database structure dependent query plan. This is used to create an SQL query that is used to evaluate the semantic query over the RDF database.

Ontology alignment is achieved using an exchange of annotations between different actors (users, software agent, application, etc.) over the Internet in order to create aligned ontologies that can be used by search engines to locate web content in the Semantic Web. An annotation related to a source ontology is received from a different storage medium. The ontology associated with that annotation is retrieved in order to make a local copy. The copied ontology is renamed before its content can be modified through a user interface. Every element modified inside the copied ontology is then automatically tagged with information in that links the modified element to the corresponding element in the source ontology. Alignment between the copied ontology and the source ontology is thereby achieved.
