    Abstract
    With the advance and growth of knowledge management in the past two decades, currently knowledge is regarded as one of the most significant organizational assets. Today the success of businesses is dependent on the value that they give to knowledge and how they attempt to manage it. Hence, in such conditions, knowledge as a valuable asset of the organization must be well-protected. What is managed in knowledge management in organizations is actually not knowledge. What are managed are the knowledge-related processes thru which knowledge workers interact with each other. Hence, organizational knowledge protection does not mean protecting knowledge, but securing the management of knowledge and... 

    A knowledge flow framework for e-government in Iran

    , Article Information Development ; Volume 32, Issue 4 , 2016 , Pages 1216-1227 ; 02666669 (ISSN) Tajgardoon, M. G ; Manzuri Shalmani, M. T ; Habibi, J ; Sharif University of Technology

    Employee commitment to innovation performance: investigating the role of knowledge acquisition and knowledge sharing

    , Article International Journal of Systematic Innovation ; Volume 7, Issue 1 , 2022 , Pages 1-17 ; 20777973 (ISSN) Sedighi, M ; Sarcheshmeh, B. S ; Bagheri, R ; Sharif University of Technology
    Society of Sytematic Innovation  2022
    Abstract
    Organisational commitment is suggested as a remarkable variable in shaping employees’ attitudes toward knowledge management practices. Customer trust in services is established during a long-time relationship with a firm and improves the accuracy of information shared with employees. To put it in other words, customer trust is what a service company needs to maintain its competitive advantage. On the other hand, high employee turnover reflects a substantial loss of knowledge. In the present study, the impact of organisational commitment on employees’ retention, knowledge acquisition, and sharing was examined regarding the moderating roles of leader-member exchange and innovation climate. The...

    Abstract
    The Putting human commonsense knowledge into computers has always been a long standing dream of artificial intelligence (AI). The cost of several tens of millions of dollars and time have been covered so that the computers could know about "objects falling, not rising.", "running is faster than walking". The large database was built, automated and semi-automated methods were introduced and volunteers' efforts were utilized to achieve this, but an automated, high-throughput and low-noise method for commonsense collection still remains as the holy grail of AI. The aim of this study was to build commonsense knowledge ontology using three approaches namely Hearst method, machine translation and...

Research limitations/implications: The study does not consider the dimension of strategic versus operational KM issues nor does it consider... 

    Towards a knowledge-based approach for creating software architecture patterns ontology

    , Article 2016 International Conference on Engineering and MIS, ICEMIS 2016, 22 September 2016 through 24 September 2016 ; 2016 ; 9781509055791 (ISBN) Rabinia, Z ; Moaven, S ; Habibi, J ; Sharif University of Technology
    Institute of Electrical and Electronics Engineers Inc  2016
    Abstract
    Software architecture patterns present solutions for software architecture problems and help to document architectural design decisions. Complexity and variability of patterns, and the required expertise for selecting an appropriate pattern, would cause some difficulties in utilizing architectural patterns. Using an ontology for registering architectural patterns is an efficient step in solving those problems. However, the mentioned difficulties make the process of constructing the architectural patterns ontology even more complicated. This paper proposes an approach that considers the construction of the architectural patterns ontology from four perspectives in order to overcome this...

    Designing and implementing basic sciences ontology based on concepts and relationships of relevant thesauri

    , Article Iranian Journal of Information Processing Management ; Volume 30, Issue 3 , Nov , 2015 , Pages 677-696 ; 22518223 (ISSN) Hosseini Beheshti, M. S ; Ejei, F ; Sharif University of Technology
    Iranian Research Institute for Scientific Information and Documentation  2015
    Abstract
    Currently, the main portion of knowledge is stored in electronic texts and documents and for transferring that knowledge effectively, we must use proper methods to gather and retrieve relevant information. Ontologies provide means to produce structured documents and use intelligent search instead of keyword search. Ontology defines the common words and concepts used to describe and represent an area of knowledge. However, developing ontologies is a time consuming and labor work. So, many ontology developers try to facilitate and speed up this process by reusing other resources. In fact, thesaurus contains semantic information and hierarchical structure that make it an appropriate resource... 

    Dynamics of knowledge accumulation in technology follower countries: A system dynamics approach

    , Article Journal of Systems Science and Systems Engineering ; Volume 18, Issue 3 , 2009 , Pages 312-340 ; 10043756 (ISSN) Shafiei, E ; Ghofrani, M. B ; Saboohi, Y ; Sharif University of Technology
    2009
    Abstract
    In this paper the process of knowledge accumulation for a particular technology is studied. Two countries, say the technology follower and the technology frontier, are considered. The frontier's knowledge growth is determined by its R&D efforts on the technology. The level of knowledge stock for the follower country is augmented by its R&D activities for the technology and absorbing some of the external knowledge through spillover from the frontier. The extent to which the follower is able to exploit the external knowledge depends on technological gap, absorptive capacity, absorption time and degree of spillover. New concepts such as natural and enhanced degree of spillover, background and...

    Designing a Knowledge Flow Modeling Framework and Introducing a Goal-Oriented Knowledge Flow Model

    , Ph.D. Dissertation Sharif University of Technology Tajgardoon, Mohammad Ghaem (Author) ; Manzuri Shalmani, Mohammad Taghi (Supervisor) ; Habibi, Jafar (Supervisor)
    Abstract
    The final goal of knowledge management is the creation of knowledge flows in a way that they sway the organization towards its goals. A knowledge flow model must take into account all kinds of horizontal and vertical flows at different levels, as well as providing support for organizational processes and goals. Because of lack of a framework for knowledge flow modeling, most models presented by researchers only cover part of these requirements. A framework for knowledge flow modeling facilitates the design of a complete and comprehensive model by considering all aspects and levels of knowledge flow. Hence, in this research, a framework for modeling of knowledge flow has been presented which...

    Abstract
    The main concern for most organizations in this age, which has been called the age of knowledge-based economy, is their success and superiority in competitive markets. Reviewing the parameters that might have been effective on the success of operationalizing a knowledge management project leads us to a potential factor as knowledge architecture. With regard to the significant effect of knowledge management in the efficiency of organizations and the inclination of current organizations toward large-scale, we try to come up with a suitable architectural framework in such organizations. The initial structure of the framework was established based on the information architectural framework of...

    Abstract
    Login section is one of the most important parts of each system. This section is usually achieved through a username-password entering method. Since in these methods, user's security relays on how strong the password is, accordingly it is important how the password is provided. There are lots of different approaches in this regard which can be categorized in two main subgroups: Static and Dynamic passwords. Dynamic passwords are taking the lead in password generation context, since static password approaches suffer from some disadvantages like their vulnerability to easily get cracked, high possibility of oblivion and etc. In this paper, we introduce a novel dynamic password providing idea,...

    Abstract
    It is widely recognized that knowledge is an essential strategic resource for a firm to achieve sustainable competitive advantage and Knowledge Management (KM) is a fundamental concept for those interested in the ever changing business world. However, KM has received little attention in Small and Medium sized Enterprises (SMEs). Unique characteristics of SMEs affect their approach in knowledge management, so different KM processes should be applied in these firms. SMEs have very simple structures, so they have less difficulty in managing their internal knowledge than large organizations. But this is not the case for external knowledge management, especially external knowledge acquisition... 

    A new way of automatic design of software (simulating human intentional activity)

    , Article 5th International Conference on New Trends on in Software Methodologies, Tools and Techniques, SoMeT_06, Quebec City, QC, 25 October 2006 through 27 October 2006 ; 2006 ; 9781586036737 (ISBN) Koono, Z ; Abolhassani, H ; Chen, H ; Sharif University of Technology
    2006
    Abstract
    This paper reports on a new method of automatic design. It is a simulation of "human intentional activity," appearing in management, business, various designs and physical work. It is achieved by repetitive hierarchical decomposition of human concepts using (mainly) natural language expressions. Three typical ways (skill, rule and knowledge based) to create the hierarchical decomposition have been implemented and evaluated quantitatively as a CASE tool. The rule-level operation achieves nearly 100% automatic detailing

    Abstract
    Successful design and implementation of knowledge management systems have been the main concern of many researchers. It has been reported that more than 50% of knowledge management systems have failed, therefore, it is required to seek for a new and comprehensive scientific approach to design and implement it. In the design and implementation of a knowledge management system, it is required to know 'what we want to achieve' and 'how and by what processes we will achieve it'. A literature review conducted and axiomatic design theory selected for this purpose. For the first time, this paper develops a conceptual design of knowledge management systems by means of a hierarchical structure,... 

    Towards an integrated framework of knowledge management between project and organization level

    , Article 9th European Conference on Knowledge Management, ECKM 2008, Southampton, 4 September 2008 through 5 September 2008 ; December , 2008 , Pages 481-490 ; 20488963 (ISSN); 9781905305537 (ISBN) Rezazadeh Mehrizi, M. H ; Tehrani, H ; Kazemi, M ; Sharif University of Technology
    2008
    Abstract
    In project-based organizations, many practical cases show there is a considerable knowledge gap between project-level and organization level. To bridge such gap, organizations can exploit knowledge intensive human resources, new organizational structures and new information and communication technologies. But all these three dimensions could have trivial effect when there is no central attention toward the content of knowledge that is to be managed. In this paper, we postulated a three layer framework for this problem that its main contribution is that the content of knowledge is at the center of attention, while all other three dimensions of any knowledge management system (HR, Organization...
