Invalidity Search for USPTO Patent Documents Using Different Patent Surrogates
This paper describes our work at the sixth NTCIR workshop on the subtask of invalidity search for patent retrieval. We compared different patent surrogates for their effectiveness on invalidity search. Our preliminary results show that the query by the Claims field plus PRF (pseudo relevance feedback) leads to the best results in terms of relevance degree A while the query by all free-text fiel...
متن کاملAutomatic Query Expansion for Patent Passage Retrieval using Paradigmatic and Syntagmatic Information
Patent text is a mixture of legal terms and domain specific terms. Patent writers tend to paraphrase standard terminology with hypernym, hyponym and synonym substitutions in order to avoid narrowing the scope of the patent invention. The practice of paraphrasing affects the exact match retrieval function negatively. There have been many success stories addressing vocabulary mismatching using ps...
متن کاملSearching for Explanatory Web Pages Using Automatic Query Expansion
When one tries to use the Web as a dictionary or encyclopedia, entering some single term into a search engine, the highly-ranked pages in the result can include irrelevant or useless sites. The problem is that single-term queries, if taken literally, underspecify the type of page the user wants. For such problems automatic query expansion, also known as pseudo-feedback, is often effective. In t...
متن کاملEffect of Log-Based Query Term Expansion on Retrieval Effectiveness in Patent Searching
In this paper we study the impact of query term expansion (QTE) using synonyms on patent document retrieval. We use an automatically generated lexical database from USPTO query logs, called PatNet, which provides synonyms and equivalents for a query term. Our experiments on the CLEF-IP 2010 benchmark dataset show that automatic query expansion using PatNet tends to decrease or only slightly imp...
متن کاملQuery Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...
