We present a study aimed at investigating the use of semantic information in a novel NLP application, Electronic Career Guidance (ECG), in German. ECG is formulated as an information retrieval (IR) task, whereby textual descriptions of professions (documents) are ranked for their relevance to natural language descriptions of a person’s professional interests (the topic). We compare the performance of two semantic IR models: (IR-1) utilizing semantic relatedness (SR) measures based on either wordnet or Wikipedia and a set of heuristics, and (IR-2) measuring the similarity between the topic and documents based on Explicit Semantic Analysis (ESA) (Gabrilovich and Markovitch,. | What to be - Electronic Career Guidance Based on Semantic Relatedness Iryna Gurevych Christof Muller and Torsten Zesch Ubiquitous Knowledge Processing Group Telecooperation Darmstadt University of Technology Hochschulstr. 10 64289 Darmstadt Germany http gurevych mueller zesch @ Abstract We present a study aimed at investigating the use of semantic information in a novel NLP application Electronic Career Guidance ECG in German.

Not well informed decisions may cause people to drop the training program they are enrolled in yielding loss of time and financial investments. However there is a mismatch between what people know about existing professions and the variety of professions which exist in reality. Some studies report that school leavers typically choose the professions known to them such 1032 as policeman nurse etc. Many other professions which can possibly match the interests of the person very well are not chosen as their titles are unknown and people seeking career advice do not know about their existence . electronics installer or chemical laboratory worker. However people are very good at describing their professional interests in natural
