Detecting Meaningful Compounds in Complex Class Labels [chapter]

Heiner Stuckenschmidt, Simone Paolo Ponzetto, Christian Meilicke
2016 Lecture Notes in Computer Science  
In this paper, we investigate the problem of automatically detecting meaningful compounds in such complex class labels to support methods that require an automatic understanding of their meaning such as  ...  Real-world ontologies such as, for instance, those for the medical domain often represent highly specific, fine-grained concepts using complex labels that consist of a sequence of sublabels.  ...  Conclusions and Future Work In this paper we presented an approach to detect meaningful compounds within complex ontology class labels.  ...

Therefore, it is critical that the toxicological relevance of EDCs and PPCPs be deter- mined in order to develop an appropriate target compound list and to establish meaningful method detection limits  ...  Thus individual compounds or complex mixtures can be tested at various concen- trations until the concentration required to displace 50% of the labeled ligand (ECs,) is determined.  ... 

Advantages and Pitfalls of Mass Spectrometry Based Metabolome Profiling in Systems Biology

Ina Aretz, David Meierhofer
2016 International Journal of Molecular Sciences  
Mass spectrometry-based metabolome profiling became the method of choice in systems biology approaches and aims to enhance biological understanding of complex biological systems.  ...  No software tool is capable of comprehensively translating all the data into a biologically meaningful context yet.  ...  Many critical parameters, such as the discrepancy between the low number of detected metabolites versus the real number of possible metabolites, the bias against compound classes and the overlap of compartmentalized  ...

Emotion detection in task-oriented spoken dialogues

L. Devillers, L. Lamel, I. Vasilescu
2003 2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat. No.03TH8698)  
About 11% of the utterances are annotated with non-neutral emotion labels. Preliminary experiments using lexical cues detect about 70% of these labels.  ...  We make use of a corpus of real agent-client spoken dialogs in which the manifestation of emotion is quite complex, and it is common to have shaded emotions since the interlocutors attempt to control the  ...  Despite the complexity involved, in our opinion it is crucial to work on real-life data. Emotion detection requires first identifying and validating emotion labels.  ...

Chemical Similarity Enrichment Analysis (ChemRICH) as alternative to biochemical pathway mapping for metabolomic datasets

Dinesh Kumar Barupal, Oliver Fiehn
2017 Scientific Reports  
Today, metabolomics datasets often contain 500-800 structurally identified compounds, for example in biomedical research 17-23 , including tumor tissues 24 .  ...  Third, for many identified compounds, especially lipids, substrate-enzyme relationships have not been unambiguously defined 40 . Fourth, many metabolites appear  ...  However, pure chemical similarity clusters are difficult to name by intelligible, biologically or chemically meaningful class labels.  ...

Learning Semantic Composition to Detect Non-compositionality of Multiword Expressions

Majid Yazdani, Meghdad Farahmand, James Henderson
2015 Proceedings of the 2015 Conference on Empirical Methods in Natural Language Processing  
We present methods of non-compositionality detection for English noun compounds using the unsupervised learning of a semantic composition function.  ...  We show that enforcing sparsity is a useful regularizer in learning complex composition functions.  ...  As mentioned earlier, overly powerful learners overfit and do not produce meaningful errors for the detection task.  ...
