摘要： Opinions about a topic are extracted from a corpus of text documents. Opinions are extracted based on rules defining regular expressions for parts-of-speech tags. Opinions are grouped based on their semantic orientation as favorable, unfavorable or neutral. A balanced and accurate assessment of sentiment towards a topic can thus be determined.
摘要翻译：关于主题的意见是从文本文档的语料库中提取出来的。根据为词性标签定义正则表达式的规则提取意见。意见根据其语义取向分为有利的，不利的或中立的。因此可以确定对话题情绪的平衡和准确的评估。

摘要： A system and method to distribute computation for an exchange in which advertisers buy online advertising space from publishers. The exchange maintains submarkets, each containing a subset of the ad calls supplied by publishers and a subset of the offers and budgets representing demand from advertisers. Portfolio optimization techniques allocate the supply of ad calls from publishers over the submarkets, with the goal of maximizing profits for publishers while limiting the volatility of those profits. Portfolio optimization techniques allocate the demand from advertisers over the submarkets, with the goal of maximizing return on investment for advertisers. The exchange re-allocates supply and demand over submarkets periodically. Also, periodically, the most effective submarkets are replicated and the least effective submarkets are eliminated.

摘要： A method and apparatus for creating templates for electronic documents is provided. One or more attributes are extracted, using a seed template, from a first document, such as a web page. A second document that contains a particular attribute, extracted from the first document, is identified. The second document may be in a different cluster than the first document. The second document is annotated, using an extracted attribute, to create an annotated document. The second document is annotated without human intervention. A new template for the annotated document is generated. The new template facilitates extraction of information from the annotated document. The new template may be used to extract additional attributes from all documents in the cluster of documents of which the second document is a member. The process may continue over numerous iterations to generate a large number of templates in an automated fashion.

摘要： A text annotation structured storage system stores text annotations with associated type information in a structured data store. The present system persists or stores annotations in a structured data store in an indexable and queryable format. Exemplary structured data stores comprise XML databases and relational databases. The system exploits type information in a type system to develop corresponding schemas in a structured data model. The system comprises techniques for mapping annotations to an XML data model and a relational data model. The system captures various features of the type system, such as complex types and inheritance, in the schema for the persistent store. In particular, the repository provides support for path navigation over the hierarchical type system starting at any type.

摘要： A decision tree may be determined that is a site map for a domain of web pages. A clustering of a plurality of web pages of a domain is determined, in an unsupervised fashion, based on content-related features of the plurality of web pages. Each determined cluster includes a plurality of web pages, each of the plurality of web pages characterized by a resource locator and each of the resource locators being characterized by at least one resource locator token. The clustering is processed to organize indications of the content-related features of the plurality of web pages into a decision tree characterized by a plurality of nodes, each node characterized by a feature and a value, the feature being at least one of the resource locator tokens and the value being a value of that resource locator token.

摘要： The present invention provides a system and a method for mining a new kind of association rules called disjunctive association rules, where the antecedent or the consequent of a rule may contain disjuncts of terms (XY or X⊕Y). Such rules are a natural generalisation to the kind of rules that have been mined hitherto. Furthermore, disjunctive association rules are generalised in the sense that the algorithm also mines rules which have disjunctions of conjuncts (C(AB)(DE)). Since the number of combinations of disjuncts is explosive, we use clustering to find a generalized subset. The said clustering is preferably performed using agglomerative clustering methods for finding the greedy subset.

摘要： The World Wide Web (WWW) can be modelled as a labelled directed graph G(V,E,L), in which V is the set of nodes, E is the set of edges, and L is a label function that maps edges to labels. This model, when applied to the WWW, indicates that V is a set of hypertext documents or objects, E is a set of hyperlinks connecting the documents in V, and the edge-label function represents the anchor-text corresponding to the hyperlinks. One can find a probabilistic ranking of the nodes for any given label, a ranking of the labels for any given node, and rankings of labels and pages using flow based models. Further, the flows can be computing using sparse matrix operations.
