This reality has led IS researchers to investigate various text mining techniques. This essay examines four text mining methods that are frequently used in order to identify their advantages and limitations. The four methods that we examine are (1) latent semantic analysis, (2) probabilistic latent semantic analysis, (3) latent Dirichlet allocation, and (4) the correlated topic model. We compare these four methods and highlight the optimal conditions under which to apply the various methods. Our paper sheds light on the theory that underlies text mining methods and provides guidance for researchers who seek to apply these methods.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115208777","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 enables diversification as well as transparency in costs and services vis-a-vis the customer to be achieved. Such services however, appear too customer specific for a standardized service provision within the context of IT-industrialisation as they are subject to constantly changing customer demands. To combat this, a concept is envisaged that keeps business process orientated IT-services modifiable and configurable by concretely defining additional Associate Services in advance. In order to maintain transparency and influence in IT expenses, these services orientate themselves towards business objects in the customer's business. The concept is illustrated with the aid of examples from its application and further development together with two associate IT-providers.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115240897","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}

To ensure price-competitive IT services over the life of the contract, client firms often rely on price benchmarks, whereby a third-party assesses the prevailing market price for the service. We provide a model to inform firms on the optimal timing and valuation of price benchmarks and assess the value of market price information for IT services. We find that IT service-level agreement (SLA) price benchmarks are most valuable for long-term contracts with significant price drift. We find that IT services price transparency is valuable where there is uncertainty about the price drift of IT services. We provide managerial recommendations based on our model for IT service price benchmarks.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124168084","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}

Today's UML modeling tools support sophisticated version management for managing parallel and distributed modeling.

There is also a growing interest in accounting for human values and norms. This paper takes a universal perspective informed by discourse ethics and it argues that value and norm issues cannot be fully resolved in the design process and that they require the continuous participation of users in use time. On the other hand, the increasing complexity in global contexts necessitates exploiting machine intelligence to adapt the system behavior to the interaction context. This paper comments on two complementary reflective principles for interactive systems (i.e., the meta-adaptation and meta-communication principles) and argues that both principles need to be implemented as system's features to support computer's as well as users' reflections.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114691609","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}

We argue that, although collaborative engineering tasks have been highly internationalized, communication media development for the pervasive global technological activities has not been sufficient, and thus when complex product design in connection with numerous technological issues is discussed on computer-mediated communication, the challenges can be more. This study conducted a multiple-case study approach, involving four case studies regarding inter-organizational collaborations on high-tech product developments. Participant observation was employed as the primary method of data collection, and extensive data was collected and analyzed. This research has found that high reliance on email communication among the participant organizations ultimately contributed to conflict occurrence, and the research findings for theoretical and practical implications are discussed.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115096426","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}

Low counts drastically affect the incidence and mortality rates of the data, leading to skewed statistics. In order to more accurately report the data, various levels of aggregation have been used (grouping counties by population, age percentages, etc.); however, such data aggregation methods have often been ad hoc and/or time consuming. Such groupings are performed on a user defined basis; however, grouping based purely on population demographics does not take into account the spatial relationships between data. Furthermore, researchers want to search for spatiotemporal correlations within their data domain. In this work, we introduce a visual analytics system for exploring cancer care statistics in a series of linked views and interactive user interface queries. We also apply the AMOEBA algorithm [1] for clustering counties based on population demographics in a visual analytics environment. Users select the population demographics field on which they wish to cluster, and these county clusters then form the basis for the data aggregation. Such a system allows the user to group their data by fields (age, gender, income) while maintaining spatial structure and provides and interactive mapping system in which to compare and explore such groupings. By utilizing such geographical groupings, we hope to better enhance the underlying structure of the data and help alleviate reporting problems associated with small area statistics.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117206060","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}
