| "text": "This short paper reports on the current state of a student software project aiming at supporting the automatized classification of folktales along the line of the classification proposed by Hans-J\u00f6rg Uther (2004) . This classification scheme is considered as a central source for the analysis work of folklorists. It builds on former work by Antti Aarne (1961) and Stith Thompson (1977) . In the following, we are using the acronym ATU for referring to (Uther, 2004) : ATU standing for Aarne-Thompson-Uther. We focus in the current work on the detection of common superclasses to the naming of the main actors (or characters) that are mentioned in the various types of folktales listed by Uther (2004) . In doing this we are able to propose more generic classes of characters and an extended vocabulary, and so to link to other classification systems, like the Motif-Index of Folk-Literature proposed by Stith Thompson 1 . In general, we are aiming at a WordNet 2 based generation of lexical semantic relations for building a terminology network of actors/characters mentioned in folktales. Our work is anchored in the field of Digital Humanities (DH), where there is an increased interest in applying methods from Natural Language Processing (NLP) and Semantic Web (SW) technologies to literary work.", | |

We tested for this the NLTK function \"path similarity\", which computes a measure on the basis of the respective length of the path needed for each synset to the shared LCH. For \"man.n.01\" and \"fox.n.05\" the function \"path similarity\" gives '0.2', while for \"fox.n.01\" and \"jackal.n.01\" it gives '0,33'. We might have '0,33' as a threshold for accepting the selected hypernym as a relevant generalization of the words used in the patterns of ATU we are investigating. Or allowing also lower similarity measures, but filtering out the selected hypernym on the basis of the length of the path leading from it to the root node. The LCH \"canine.n.02' has a much longer path to \"entity\" as does the LCH \"person.n.01\".

The last element of the code, introduced by \"rdfs:label\", stores the original label in English (\"en\"). We will use this property \"rdfs:label\" to encode the multilingual correspondences. We encode the original description of the type as a value to the property \"rdfs:isDefinedBy\". The property \"linkToTMI\" is the way we go for linking ATU types to Motifs listed in the Motif-Index of Folk-Literature (which we abbreviate with TMI). This linking is still in a preliminary stage, since we first have to finalize the corresponding TMI ontology, and also check the validity of the linking to TMI we extracted from the ATU book. This kind of linking is the one we will use for interconnecting all types of classification schemes used for folktales (and maybe also for other literary genres). We will add a property for including relevant hypernyms (and possibly hyponyms) extracted from WordNet to the current labels, contributing this way to the semantic enrichment of the original classification.", | |

The aim is to generate a WordNet based network of terms for the folktale domain.", | |

We will also perform an evaluation of the extracted LCHs against a manually annotated set of ATU entries. And we will compare the French equivalents of the synsets proposed by WordNet with the French terms used in the French Wikipedia page for the AT. Additionally, we plan to compare our WordNet based approach as the basis for the linking between ATU and TMI to the machine learning approach to such a linking described in (Ofex et al., 2013) .", | |
