Use of A Domain-Specific Ontology to Support Automated Document Categorization at the Concept Level: Method Development and Evaluation

[Id]Sebuah dokumen berita seringkali terkait lebih dari satu kategori, untuk itu diperlukan pemanfaatan metode kategorisasi yang tidak hanya cepat tetapi juga dapat mengelompokkan sebuah berita kedalam banyak kategori. Banyak metode yang dapat digunakan untuk mengkategorisasi dokumen berita, salah satunya adalah ontologi. Pendekatan ontologi dalam kategorisasi sebuah dokumen berita didasarkan pada kemiripan fitur yang ada di dokumen dengan fitur yang ada di ontologi. Penggunaan ontologi dalam kategorisasi yang hanya didasarkan pada kemunculan term dalam menghitung relevansi dokumen menyebabkan banyak kemunculan fitur lain yang sebenarnya sangat terkait menjadi tidak terdeteksi. Dalam? paper ini diusulkan? metode baru untuk kategorisasi dokumen berita? yang terkait dengan banyak kategori, metode ini berbasis domain specific ontology yang perhitungan relevansi dokumen terhadap ontologinya tidak hanya didasarkan pada kemunculan term tetapi juga memperhitungkan relasi antar term yang terbentuk. Uji coba dilakukan pada dokumen berita berbahasa indonesia dengan 2 kategori yaitu olahraga dan teknologi. Hasil uji coba menunjukkan nilai rata-rata akurasi yang cukup tinggi yaitu kategori olahraga adalah 93,85% sedangkan pada kategori teknologi adalah 96,32%.Kata Kunci: Dokumen berita, kategorisasi, multi-label, ontologi,? domain-spesifik.[En]A news document often related? to more than one category,? necessary for utilization? the method of categorization that is not only fast but also able to Classify a news into many categories. Many methods can be used to categorize the news documents, one of which is an ontology. Ontology approach in the categorization of a document is based on the similarity of news features in documents with features that exist in the ontology. The use of ontologies in categorization that just based on the occurance of the term in calculating the relevance of the document, led to the emergence of many other fea-tures that are actually very relevant is undetectable. This paper proposed a new method for categorizing news documents are related with many categories, the method is based on a specific domain ontology and for document relevance calculation is not only based on the occurrence of the term but also take into account the relationships between terms that are formed. Tests performed on the Indonesian language news document with? two categories: sports and technology. The trial results show the value of the average accuracy is high, that the sports category was 93,85% and the technology category is 96,32%.Keywords : News document, ?categorization, multi-label, Ontology, domain-specific.

Problem Solving Task

This study compared individuals with pairs in a scientific problem-solving task. Participants interacted with a virtual psychological laboratory called Virtue to reason about a visual search theory. To this end, they created hypotheses, designed experiments, and analyzed and interpreted the results of their experiments in order to discover which of five possible factors affected the visual search process. Before and after their interaction with Virtue, participants took a test measuring theoretical and methodological knowledge. In addition, process data reflecting participants’ experimental activities and verbal data were collected. The results showed a significant but equal increase in knowledge for both groups. We found differences between individuals and pairs in the evaluation of hypotheses in the process data, and in descriptive and explanatory statements in the verbal data. Interacting with Virtue helped all students improve their domain-specific and domain-general psychological knowledge.

Abstract. Our unit investigates the relationship of emotional processes (experience, expression, and coping), their physiological correlates and possible health outcomes. We study domain specific anger expression behavior and associated cardio-vascular loads and found e.g. that particularly an open anger expression at work is associated with greater blood pressure. Furthermore, we demonstrated that women may be predisposed for the development of certain mental disorders because of their higher disgust sensitivity. We also pointed out that the suppression of negative emotions leads to increased physiological stress responses which results in a higher risk for cardiovascular diseases. We could show that relaxation as well as music activity like singing in a choir causes increases in the local immune parameter immunoglobuline A. Finally, we are investigating connections between migrants’ strategy of acculturation and health and found e.g. elevated cardiovascular stress responses in migrants when they where highly adapted to the German culture.

Confirmatory Factor

The present study explores the factorial structure and the degree of measurement invariance of 12 divergent thinking tests. In a large sample of German students (N = 1328), a three-factor model representing verbal, figural, and numerical divergent thinking was supported. Multigroup confirmatory factor analyses revealed that partial strong measurement invariance was tenable across gender and age groups as well as school forms. Latent mean comparisons resulted in significantly higher divergent thinking skills for females and students in schools with higher mean IQ. Older students exhibited higher latent means on the verbal and figural factor, but not on the numerical factor. These results suggest that a domain-specific model of divergent thinking may be assumed, although further research is needed to elucidate the sources that negatively affect measurement invariance.
