Data sparsity is a long-standing challenge for recommender systems based on collab.rative filtering. A promising solution for this problem is multi-context recommendation, i.e., leveraging users' explicit or implicit feedback from multiple contexts. In multi-context recommendation, various types of interactions between entities (users and items) are combined to alleviate data sparsity of a single context in a collective manner. Two issues are crucial for multi-context recommendation: (1) How to differentiate context-specific factors from entity-intrinsic factors shared across contexts? (2) How to capture the salient phenomenon that some entities are insensitive to contexts while others are remarkably context-dependent? Previous methods either do not consider context-specific factors, or assume that a context imposes equal influence on different entities, limiting their capability of combating data sparsity problem by taking full advantage of multiple contexts. In this paper, we propose a context-adaptive matrix factorization method for multi-context recommendation by simultaneously modeling context-specific factors and entity-intrinsic factors in a unified model. We learn an entity-intrinsic latent factor for every entity, and a context-specific latent factor for every entity in each context. Meanwhile, using a context-entity mixture parameter matrix we explicitly model the extent to which each context imposes influence on each entity. Experiments on two real scenarios demonstrate that our method consistently outperforms previous multi-context recommendation methods on all different sparsity levels. Such a consistent performance promotion forms the unique superiority of our method, enabling it to be a reliable model for multi-context recommendation. © 2015 ACM.

This study investigates factors that may determine satisfaction in customer service operations. We utilized more than 170,000 online chat sessions between customers and agents to identify characteristics of chat sessions that incurred dissatisfying experience. Quantitative data analysis suggests that sentiments or moods conveyed in online conversation are the most predictive factor of perceived satisfaction. Conversely, other session related meta data (such as that length, time of day, and response time) has a weaker correlation with user satisfaction. Knowing in advance what can predict satisfaction allows customer service staffs to identify potential weaknesses and improve the quality of service for better customer experience. © 2015 ACM.

Neuroscientists have investigated into the functional-structural mechanisms of sleep for a long time. However, the sleep physiology is so complex that the relations to brain structure are still mostly unknown. In this paper, we integrate the brain sleep switch model with fuzzy methodology, more specifically, combining the the mutual inhibition system of the sleep switch with a rule-based fuzzy reasoning system. Based on the extension of sleep switch, a model for sleep physiological dynamics is proposed. In addition, we implement the sleep mechanisms and integrate them into an object-oriented brain simulator. With the brain simulator, we can demonstrate sleep dynamics of the brain network with 3D-rendering system is demonstrated. The sleep physiological dynamics in brain become more intuitive and easier to realize. © 2012 Springer-Verlag.

Most sleep management systems lack reliable assessment of sleep quality and receive single information source only. In this paper, we proposed a sleep quality assessment mechanism based on the physiological sleep pattern with scenarios of multiple data sources. This mechanism provides an intuitive personalized sleep quotient which encourages users to have long-term usage of sleep management service. It further helps users to understand their sleep patterns and adjust sleep habits. In addition, sleep medical professionals can strengthen the diagnostic judgment with this assessment mechanism. © 2012 IEEE.

How to design an efficient and cost effective software system is a million dollar question to every software engineer. The challenges lie in the fact that there is no such fixed rules and regulations, following which will produce an efficient software system. Practitioners have proposed many solutions to address this issue. In this discussion, we will try to touch base on some of the vital points which a practitioner is encouraged to adapt in order to lead a team of software engineers to produce cost effective efficient system. © 2010 IEEE.

An important component of any web search engine is its crawler, which is also known as robot or spider. An efficient set of crawlers make any search engine more powerful, apart from its other measures of performance, such as its ranking algorithm, storage mechanism, indexing techniques, etc. In this paper, we have proposed an extended technique for crawling over the World Wide web (WWW) on behalf of a search engine. This is an approach with multiple crawlers working in parallel combined with the mechanism of focused crawling (Chakrabarti et al., 1999a, 2002;Mukhopadhyay et al., 2006). In this approach, the total structure of any website is divided into several number of levels based on the hyperlink-structure for downloading web pages from that website (Chakrabarti et al., 1999b;Mukhopadhyay and Singh, 2004). The number of crawlers of each level is not fixed, rather dynamic in this context. It is determined at execution time on demand basis using threaded program based on the number of hyperlinks of a specific web page. This paper also proposes a focused hierarchical crawling technique, where crawlers are created dynamically at runtime for different domains to crawl the web pages with the essence of resource sharing.

web search engine uses indexing for management of web-pages in a mannered way. web-pages are well distributed within the database of server. Both forward and inverted indexing is employed to tackle web-pages as a part of its functional design. This indexing mechanism helps in retrieving data from the database based on user query. In this paper, an efficient solution to handle the indexing problem is proposed with the introduction of non-linear single cycle multiple attractor cellular automata (SMACA). This paper also reports an analysis on SMACA using rule vector graph (RVG). This work simultaneously shows generation of SMACA by using specific rule sequence. Searching mechanism is done with O(n) complexity. SMACA provides an implicit memory to store the patterns. Search operation to identify the class of a pattern out of several classes boils down to running a cellular automata (CA) for one time step. This demands storage of the CA rule vector (RV) and the seed values. SMACA is based on sound theoretical foundation of CA technology. © 2008, Inderscience Publishers.

Software development is tightly dependent on the tools availab.e for supporting its processes. Organizational and sociotechnical peculiarities such asindefinition of roles, geographically distributed development teams, new business models and diverse cultural interactions steer these tools. Software development supported by web-based services, built on top of web 2.0 technologies, is emerging as a new paradigm for distributed software development. New generation software forges (web-based development environments) such as EzForge are becoming the infrastructure that provides the required features for hosting collections of software development projects. They are composed of an integrated set of tools, interacting in a mashup-like environment, each one suited for a specific task, and therefore simple enough to keep total complexity low. An adequate selection of tools helps developers to focus on the implementation of the requirements, while at the same time they cope with complex information coming from many individuals and organizations. The complexity of distributed software development requires a controlled and a strong collab.ration amongst developers, which has to be supported by the selected architecture. Moreover, an increased demand on quality assurance is required by the many organizations aiming to achieve a certain quality level. A new architecture based on the web 2.0 core ideas and methods overcomes these challenges in software development, representing a cornerstone to achieve satisfactory results in this ambitious environment. © 2008 IEEE.
