Text clustering is important in many application of information retrieval. This paper presents a study of clustering short texts in Bahasa Indonesia using semantic similarity approach where dictionary of synonyms and hyponyms is used to get information on word relatedness. We compare sentence similarity calculations based on lexical matching and word similarity. More than 250 sentences are involved...
The paper proposes a mobile robot platform that uses Robot Operating System as a core and aims at improving the educational experience of computer science courses. In comparison to other education robotics projects, the advantage of our platform is a bundle of smart engineering solutions that allow simulating sensors using a single camera. The field of camera's view covers the whole platform and the...
Source code analyzer is a tool for analyzing source code that aim to improve the quality of programs in software development. This research enhanced the ability of source code analyzer for automatic grading of programming assignments. The automatic grading process runs in three phases: (a) source code analysis by source code analyzer, (b) analytical results unification, and (c) unification results...
Malaria is one of the tropical diseases, which is found with high prevalence in East side of Indonesia. To assist the diagnosis of this disease, we have developed a Computer Aided Diagnosis system that analyze the information obtained from thin blood smears microphotograph. Five species of the parasites are found in Indonesia, and each of them has different morphology. Therefore, the morphological...
Recognizing textual entailment (RTE) is a task that predict whether a text fragment can be inferred from another text fragment. In this paper, we tackle RTE problem using sentence extraction to cover semantic variation and then extracting subject, predicate and object from each sentence without using external resources like Wordnet. Finally, similarity function is used to predict entailment relation...
Upwelling is an océanographie phenomenon where the mass of water from the sea floor, cold temperature and nutrient rich, moving up to the sea surface Upwelling could be happened due to the interaction between the surface water with the wind, ocean currents, Ekman transport, and the Coriolis force, so there is a special characteristic of the upwelling waters. Nevertheless, a common indicator of upwelling...
Adaptable Model Versioning (AMOR) is a framework intended to be adapted for versioning of model artefacts. AMOR framework is known for some limitations in the operation and conflict detection process, as well as in the conflict resolution process. This paper presents an attempt to improve AMOR framework using Critical Pair Analysis (CPA), a computation conducted to determine potential conflicts between...
Classification is a technique in data mining for categorizing objects. Text Classification is re-challenged for classifying very short documents or text as shown in social media collection. This paper proposes a method to improve the performance of classification on short documents. In this work, we expand words in every document before the documents are classified We use TFIDF model, Hidden Markov...
In an organization, the executive have duty to analyze situation based on data. By doing so, the executive is expected to make a right decision which will increase the performance of organization. To support executive in this decision-making activity, a summary report which is obtainable through the Executive Information System (EIS) can be used. In its usage, the EIS can be integrated with old information...
Offshore IT outsourcing has been very popular in the last 20 years as the companies want to concentrate more on its core business processes. According to A.T. Kearney Global Position Index for the year 2011, Indonesia ranks fifth in terms of attractiveness as an offshore IT outsourcing service provider. To enhance the competitiveness of the IT companies in Indonesia, a good understanding of the capabilities...
Modern car engine has a control unit that serves to control all aspects of the car known as the Engine Control Unit (ECU). The control unit was developed by the manufacturer to assist in optimizing engine performance, and has proven to be very useful Unfortunately, the existence of ECU means independent repair shops can't do engine repair and maintenance without help from manufacturer. This paper...
Spatio-temporal databases technology have evolved to track moving objects. Objects or data that are well-defined will be easier to be manipulated but some data have attributes that can't be predicted so it needs additional handling technique to be able to adapt with the current system. This paper proposes architecture of a prototype for unpredictable data and moving object handling in a spatio-temporal...
Traffic jam is one of the big and complex problems which happens in many big cities around the world. The advances in technology have enabled tracking moving objects such as vehicles move on road networks. Those data is called spatio-temporal data. By using data mining techniques, analysis on traffic characteristics can be conducted to detect potential area of traffic jam. This information is particularly...
We present in this paper a new Direct Access Framework (DAF) for speaker identification system, to identify a speaker based on original characteristics of the human voice. Direct access method is a process to identify an object based on parts of the object itself, the parts called original characteristics. The proposed framework consists of two parts, the enrolment process and the identification process...
Web search results often consist of web results and news results. News results are displayed based on measurement of click-through Rate (CTR), a comparison between clicks and views of content. In other words, the more clicks obtained by content, the probability of that content appear, as news results will be higher. The CTR measurement is not effective for recent news due to recent news only have...
Indonesia have a massive number of SMEs, but with a very low revenue. An alternative to increase revenue is by using internet. Some SMEs already develop their website, but they don't have same navigation. The websites confuse the potential buyers. So, a website's aggregator is essential. This aggregator is made without the owner of the SMEs to register their website, which means it can automatically...
Requirements change is an inevitable activity and can occur due to changes in user demands, increased understanding of the stakeholders, customer organization, project vision, requirements specification and availability of technological solutions. Although requirements change management (RCM) is not a straightforward process in collocated software development, the presence of geographical, social,...
