Sinonasal-inverted papilloma is a benign tumour with a high rate of recurrence, but possible malignant transformation. Therefore, investigation of predisposition to malignant transformation of sinonasal-inverted papilloma gives clinicians the opportunity for adequate treatment. Topoisomerase II-alpha (topoII-alpha) and Ki67 are markers of cell proliferation in both normal and neoplastic tissues...

We examine the search of partitioned inverted files with particular emphasis on issues that arise from different types of partitioning methods. Two types of index partitions are investigated: namely Termld and Docld. We describe the search operations implemented in order to support parallelism in probabilistic search. We also describe higher level features such as search topologies in parallel ...

We previously proposed [1] fast spoken term detection that uses a suffix array as a data structure for searching a largescale speech documents. In this method, a keyword is divided into sub-keywords, and the phoneme sequences that contain two or more sub-keywords are output as results. Although the search is executed very quickly on a 10,000-h speech database, we only proposed a variety of matc...

On the Semantic Web, the types of resources and the semantic relationships between resources are defined in an ontology. By using that information, the accuracy of information retrieval can be improved. In this paper, we present effective ranking and search techniques considering the semantic relationships in an ontology. Our technique retrieves top-k resources which are the most relevant to qu...

Compression of inverted lists with methods that support fast intersection operations is an active research topic. Most compression schemes rely on encoding differences between consecutive positions with techniques that favor small numbers. In this paper we explore a completely different alternative: We use Re-Pair compression of those differences. While Re-Pair by itself offers fast decompressi...

In this paper, we argue that specificational copular clauses are derived equations which are distinct from genuine equatives. While the latter has an equative copula, the former achieves a semantics of equation through type-shift. The account presented here not only allows us to maintain a predicate inversion analysis for specificational copular clauses but also explain when a predicate can be ...

This paper describes our entry into the TREC 2011 Web track. We extracted and ranked results from the ClueWeb09 corpus using a parallel processing pipeline that avoids the generation of an inverted file. We describe the components of the parallel architecture and the pipeline, how we ran the TREC experiments, and we present effectiveness results.

This paper presents a structure we call XML Wavelet Tree (XWT) to represent any XML document in a compressed and self-indexed form. Therefore, any query or procedure that could be performed over the original document can be performed more efficiently over the XWT representation because it is shorter and has some indexing properties. In fact, XWT permits to answer XPath queries more efficiently ...

Information retrieval over clustered document collections has two successive stages: first identifying the best-clusters and then the best-documents in these clusters that are most similar to the user query. In this paper, we assume that an inverted file over the entire document collection is used for the latter stage. We propose and evaluate algorithms for within-cluster searches, i.e., to int...
