Yet, in the agile RE literature, very little is known about how agile reprioritization happens in practice. Generic conceptual models about this process are missing, which in turn, makes it difficult for both practitioners and researchers to reason about requirements decision-making at inter-iteration time. This paper presents a Grounded Theory study on agile requirements prioritization methods to yield a conceptual model for understanding the inter-iteration prioritization process in terms of inputs and outcomes. The latter is derived by using qualitative empirical data, published earlier by other authors. Such a conceptual model makes explicit the concepts that are used tacitly in different agile requirements prioritization methods and can be used for structuring future empirical investigations about this topic.","PeriodicalId":333366,"journal":{"name":"2010 Fourth International Conference on Research Challenges in Information Science (RCIS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123700914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, simple search approaches are still frequently used. A simple keyword or thesauri-based search is efficient and can be easily scaled. However, keyword-based search cannot be used to infer what may or may not be relevant to the user and thesauri, or any other expert generated model, is expensive to produce and tends to be of limited applicability. Semantic Component Selection (SemaCS) approach is not tied to any specific domain and does not rely on expert input. SemaCS is based on actual data and statistical semantic distances between words. Information on semantic distances is used for searching and for automated generation of domain model taxonomy. This paper presents SemaCS's means of acquiring these semantic distances - mNGD (2) - and its initial evaluation.","PeriodicalId":333366,"journal":{"name":"2010 Fourth International Conference on Research Challenges in Information Science (RCIS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115061564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is not yet a holistic approach and no unified adaptive and time-variant model addressing the problem. A model for assessing both initiatives and ex-post evaluation is needed. In this paper, we describe a model called the Strategic Management Model, developed and partially applied at the Ministry of Finance, Turkey. The model merges public value, strategic goals, service delivery value chain, performance indicators, continuous monitoring & evaluation, internal control / audit and asset management concepts in Public Financial Management hypercube. This is compliant with Government Finance Statistics, with orthogonal dimensions, in which every node and path is defined as an object within this value space. This adaptive model will allow for multi-dimensional assessment based on hypercube, enabling forward and backward traceability from goals to planned budget, and from expenditure to goals.","PeriodicalId":333366,"journal":{"name":"2010 Fourth International Conference on Research Challenges in Information Science (RCIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129733774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It builds upon the idea of deriving similarity from deviations between the pattern sequence and its best-possible representation in the candidate sequence. Which representation is considered optimal solely depends on the analyst's current focus and interest; the model thus foresees highest configurability to adequately balance aspects such as single-event similarities, order, timing, and missing events. The model is furthermore applicable for both sub-sequence searching and full-sequence matching. As an extension to the base model, we discuss enhanced patternmodeling facilities, e.g., to ensure a maximal time interval between two or more candidate events. The proposed tree-search algorithm allows for a seamless integration of such extensions.","PeriodicalId":333366,"journal":{"name":"2010 Fourth International Conference on Research Challenges in Information Science (RCIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129800411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some approaches have been proposed for integrating the evolution issue at the architectural level. However, none of these studies the impact assessment between the software architecture and its related source code. To deal with that, we propose a model, called ASCM (Architectural Software Components Model), on which we define our change propagation process. Our model describes the common elements defined in an architecture description, independently of architecture description languages (ADLs). The change propagation process is based on a knowledge-based system, in which the model instances are stored. When a modification is applied on these, propagation rules are fired to simulate the impact on software architecture and on its source code. This is done using a platform developed on the top of Eclipse Environment.","PeriodicalId":333366,"journal":{"name":"2010 Fourth International Conference on Research Challenges in Information Science (RCIS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132509582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For doing so, we have replaced the “support” threshold criterion of the well-known Apriori algorithm by a “number of liberties”: the liberty count expresses how a (k+1)-level itemset is constrained by its k-level “parents”, till the level when the situation turns frozen. Our algorithm is symmetric: we take into account the absence of items as well as their presence in our itemsets. Conversely, we present a method for reconstituting the original data starting from our exact MIDOVA representation. We illustrate these points with the examples of Breast Cancer and Mushroom datasets from UCI Repository. We validate our approach by deriving a learning classifier approach and applying it to three discrimination problems drawn from the above-mentioned repository.","PeriodicalId":333366,"journal":{"name":"2010 Fourth International Conference on Research Challenges in Information Science (RCIS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133467200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a knowledge-based efficiency assessment system for distribution network using data envelopment analysis (DEA). From an input-output view, DEA method is used to calculate the efficiency of distribution lines and obtain gap information. Knowledge base is used to store facts and rules, facts include input-outputs data of DEA and other information about structure and operation of distribution lines. The rules can be empirical rules from domain expert or extracted from industry guidelines or government standards by knowledge worker. Considering the service requirements of power supply in rules, DEA assessment results can be effectively used or provided in the solution of improvement by reasoning. The knowledge base technology and DEA integration represents a step towards a real challenge of the near future. In this system, the final decision is based on DEA assessment results and reasoning. The suggested solution can assist decision maker in making planning to further strengthen distribution network in an efficient and effective manner.","PeriodicalId":333366,"journal":{"name":"2010 Fourth International Conference on Research Challenges in Information Science (RCIS)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114737054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
