This game introduces a new business model that makes it possible for players to present their artworks in virtual kiosks using augmented reality, while they are having fun playing the game. In addition to competition between the play...

Data exchange is the process of generating an instance of a target schema from an instance of a source schema such that source data is reflected in the target. Generally, data exchnge is performed using schema mapping, representing high level relations between source and target schemas. In this paper, we argue that data exchange solely based on sch...

Although association rule mining is an important pattern recognition and data analysis technique, extracting and finding significant rules from a large collection has always been challenging. The ability of information visualization to enable users to gain an understanding of high dimensional and large-scale data can play a major role in the explor...

Large linked data repositories have been built by leverag-ing semi-structured data in Wikipedia (e.g., DBpedia) and through extracting information from natural language text (e.g., YAGO). However, the Web contains many other vast sources of linked data, such as structured HTML tables and spreadsheets. Often, the semantics in such tables is hidden,...

By using sound to visualize the real-world environment, audio games can offer a completely new game experience. In this paper, we study how audio cues can be visualized in computer games to enhance the navigation skills of players. To this end, we propose an audio game in which blindfolded players move through a physical maze with the help of audio...

Voice and face information are two most important perceptual modalities for human. In recent years, many researchers show great interest in learning cross-modal representations for different face-voice association tasks. However, these existing methods focus on the various biological attributions but rarely take emotion semantics between voice and...

Frame breaking in traditional Persian paintings, also known as Persian miniature, is a practice where parts of the frame are intentionally left open for some painting elements to exit the frame. This repeatedly occurred in this tradition; and was used methodically in Herat and Tabriz II schools. However, the motivation behind it is not completely k...

Schema mapping is becoming pervasive in information integration through data exchange and data integration. In this paper, we show that current schema mapping generation and verification techniques are not capable of reconciling some semantic heterogeneity because of ambiguities in interpreting different types of relations. To address this problem,...

Data Exchange creates an instance of a target schema from an instance of a source such that source data is reflected in the target instance. The prevailing approach for data exchange is based on generating and using schema mapping expressions representing high level relations between source and target. We show such class level schema mappings canno...

Advances in business intelligence systems based on processing large data volumes are driving efforts toward read-optimized databases. Recently, the use of column-store approaches as a solution for such databases has become quite popular. The main idea behind the column-store approach is reducing I/O requirements through vertical partitioning of dat...

Information integration has always been a challenging issue in information management. Regardless of the implementation techniques, relations between heterogeneous data sources are stated in terms of high level specifications called schema mappings. Generally, such mappings are created using referential integrity constraints and a set of correspond...

Privacy preserving data mining (PPDM) algorithms attempt to reduce the injuries to privacy caused by malicious parties during the rule mining process. Usually, these algorithms are designed for the semi-honest model, where participants do not deviate from the protocol. However, in the real-world, malicious parties may attempt to obtain the secret v...

The method of association rule mining has been used by marketers for many years to extract marketing rules from purchase transactions. Marketers and managers employ these rules in order to predict customer needs for future sales. Extracting effective rules is one of the major problems of marketers. Effective rules can help them to make better marke...

Purpose – In traditional commerce, an auction is known as a mechanism of determining the value of a commodity that does not have a fixed price.
