In this demo paper, a SPARQL Query Recommendation Tool (called SQUIRE) based on query reformulation is presented. Based on three steps, Generalization, Specialization and Evaluation, SQUIRE implements the logic of reformulating a SPARQL query that is satisfiable w.r.t a source RDF dataset, into others that are satisfiable w.r.t a target RDF dataset. In contrast with existing approaches, SQUIRE ...

A novel method to extend flash memory lifetime in flash-based DBMS Abstract: As the capacity increases and the price drops gradually, flash memory is becoming the promising replacement of disk, even in the enterprise applications. However, flash memory suffers from erase-before-write and limited write-erase cycles at the same time, which means the abuse of write,especially small and random writ...

Entity suggestion by example (ESbE) refers to a type of entity acquisition query in which a user provides a set of example entities as the query and obtains in return some entities that best complete the concept underlying the given query. Such entity acquisition queries can be useful in many applications such as related-entity recommendation and query expansion. A number of ESbE query processi...

We present an approach to the design of personalized recommender systems that integrates content-based methods, collaborative filtering techniques and case-based reasoning while adopting a user-centered perspective. These techniques are employed to support information search and choice processes. In this framework, we developed and tested a system prototype (NutKing) that helps the user to cons...

User queries submitted to web search engines are not always informative enough for retrieving the related pages to the user intention. The main problem is that users may not know the best query items they should enter to get the most related web pages to their intentions. They may not be familiar with the specific keywords in that domain knowledge. A user may remember only a part of the phrase ...

Improving software development efficiency based on existing APIs is one of the hot researches in engineering. Understanding and learning so many large libraries not easy developers prefer to provide only requirements descriptions get right API. In order solve this problem, paper proposes an API recommendation method WII-WMD, improved similarity calculation algorithm. This firstly structures tex...

Current search and recommendation engines enable us to effectively retrieve a set of documents based on topical relevance. What is not taken into account is the knowledge a user may already have about a topic, e.g., whether information is redundant or whether he/she is able to understand the results. We propose a method to measure demonstrated potential domain knowledge (DPDK) as a proxy for kn...

histone deacetylase inhibitors have gained a great deal of attention recently for the treatment of cancers and inflammatory diseases. so design of new inhibitors is of great importance in pharmaceutical industries and labs. creating pharmacophor models in order to design new molecules or search a library for finding lead compounds is of great interest. this approach reduces the overall cost ass...
