چکیده
This paper presents the DUTIR submission to TREC 2009 Chemical IR Track. This track included two tasks: Prior Art (PA) and Technical Survey (TS) tasks. We present a series of experiments on two text retrieval models, BM25 and Language Model for IR (LMIR). For Prior Art task, we focused on formulating the queries from the query patents and date filtering. Moreover, some traditional search techniques are used for Technical Survey task.

متن کاملOverview of the TREC 2009 Chemical IR Track
TREC 2009 was the first year of the Chemical IR Track, which focuses on evaluation of search techniques for discovery of digitally stored information on chemical patents and academic journal articles. The track included two tasks: Prior Art (PA) and Technical Survey (TS) tasks. This paper describes how we designed the two tasks and presents the official results of eight participating groups.
متن کاملDUTIR at the Session Track in TREC 2011
This paper presents the DUTIR submission to TREC 2011 Session Track, the task is to test whether systems can improve their performance for a given query by using previous queries and user interactions with the retrieval system. We use language model as the basic retrieval model. Query Expansion is applied to reformulate the original query. Some other technologies like Pseudo Relevance Feedback ...

This paper details our experiments carried out at TREC 2008 Relevance Feedback Track. We focused on the analysis of feedback documents, both relevant and non-relevant, to explore more useful information to improve retrieval performance. In our experiments, local co-occurrence model and a Rocchio formula were used to select good expansion terms. Five runs were submitted. These runs used differen...
متن کاملDUTIR at TREC 2007 Genomics Track
This paper describes our experiments on TREC 2007 Genomics Track which is concerned with question answering extraction from full-text biomedical literatures. In our experiment, named entities were recognized at the preprocessing stage using a two-view method. MeSH was used to expand the terms. We performed passage retrieval by using sentence-level half overlapped sliding windows. Indri structur...
