Retrieve results

The resulting model is a Document Retriever, called QASA, which is then integrated with a machine reader to form a complete open-domain QA system. Our system is thoroughly evaluated using QUASAR-T dataset and shows surpassing results compared to other state-of-the-art methods.

We propose a content based video retrieval system in some main steps resulting in a good performance. From a main video, we process extracting keyframes and principal objects using Segmentation of Aggregating Superpixels (SAS) algorithm. After that, Speeded Up Robust Features (SURF) are selected from those principal objects. Then, the model “Bag-of-words” in accompanied by SVM classification are applied to obtain the retrieval result. Our system is evaluated on over 300 videos in diversity from music, history, movie, sports, and natural scene to TV program show.

The aim of this study is to examine whether the change of schema would affect the process of encoding and retrieval. This experiment is a modification of Anderson and Pichert’s study. The independent variable in the experiment was the two different schemas used in the study (Geography student or tourist) and the dependent variable was the extent to which the participants could recall the story, specifically the number of words in this case. The results suggested that a change in schema of the same story would improve recall, as found by Anderson and Pichert.

[, vol.8, nos.3 and 4, June and October 1965] * by , Cambridge Language Research Unit, Cambridge, England The paper describes how the need for automatic aids to classification arose in a manual experiment in information retrieval. It goes on to discuss the problems of automatic classification in general, and to consider various methods that have been proposed. The definition of a particular kind of class, or "clump," is then put forward.

After initial retrieval results are presented, allow the user to provide feedback on the relevance of one or more of the retrieved documents. Use this feedback information to reformulate the query. Produce new results based on reformulated query. Allows more interactive, multi-pass process.

Dedicated to C´sar Camacho for his 60th birthday e Abstract After gluing foliated complex manifolds, we derive a preparation-like theorem for singularities of codimension-one foliations and planar vector fields (in the real or complex setting). Without computation, we retrieve and improve results of Levinson-Moser for functions, Dufour-Zhitomirskii for nondegenerate ˙ codimension-one foliations (proving in turn the analyticity), Str´zyna-Zoladek o˙ ´ for non degenerate planar vector fields and Bruno-Ecalle for saddle-node foliations in the plane. ...

The basic set of operations for the relational model is known as the relational algebra. These operations enable a user to specify basic retrieval requests. The result of a retrieval is a new relation, which may have been formed from one or more relations. The algebra operations thus produce new relations, which can be further manipulated using operations of the same algebra.

A query expresses in a high-level language like SQL must first be scanned, parsed, and validated. • Once the above steps are completed, an internal representation of the query is created. Typically this is either a tree or graph structure, called a query tree or query graph. • Using the query tree or query graph the RDBMS must devise an execution strategy for retrieving the results from the internal files. • For all but the most simple queries, several different execution strategies are possible. The process of choosing a suitable execution strategy is called query optimization....

In Chapter 20, you built SQL statements to retrieve and update rows in a database. You also learned all the variations of the SELECT statement. Some restrictions, however, can’t be expressed with a WHERE clause, no matter how complicated. To perform complicated searches, many programmers would rather write an application to retrieve the desired rows, process them, and then display some results. The processing could include running totals, formatting of the query’s output, calculations involving multiple rows of the same table, and so on. ......
