Lexical Flexibility, Natural Language, and Ontology

The Realist that investigates questions of ontology by appeal to the quantificational structure of language assumes that the semantics for the privileged language of ontology is externalist. I argue that such a language cannot be (some variant of) a natural language, as some Realists propose. The flexibility exhibited by natural language expressions noted by Chomsky and others cannot obviously be characterized by the rigid models available to the externalist. If natural languages are hostile to externalist treatments, then the meanings of natural language expressions serve as poor guides for ontological investigation, insofar as their meanings will fail to determine the referents of their constituents. This undermines the Realist’s use of natural languages to settle disputes in metaphysics

Biomedical ontology alignment: An approach based on representation learning

While representation learning techniques have shown great promise in application to a number of different NLP tasks, they have had little impact on the problem of ontology matching. Unlike past work that has focused on feature engineering, we present a novel representation learning approach that is tailored to the ontology matching task. Our approach is based on embedding ontological terms in a high-dimensional Euclidean space. This embedding is derived on the basis of a novel phrase retrofitting strategy through which semantic similarity information becomes inscribed onto fields of pre-trained word vectors. The resulting framework also incorporates a novel outlier detection mechanism based on a denoising autoencoder that is shown to improve performance. An ontology matching system derived using the proposed framework achieved an F-score of 94% on an alignment scenario involving the Adult Mouse Anatomical Dictionary and the Foundational Model of Anatomy ontology (FMA) as targets. This compares favorably with the best performing systems on the Ontology Alignment Evaluation Initiative anatomy challenge. We performed additional experiments on aligning FMA to NCI Thesaurus and to SNOMED CT based on a reference alignment extracted from the UMLS Metathesaurus. Our system obtained overall F-scores of 93.2% and 89.2% for these experiments, thus achieving state-of-the-art results

Mood, definiteness and specificity: a linguistic and a philosophical account of their similarities and differences

In diesem Beitrag beschreiben wir aus linguistischer Perspektive das Verhältnis von einigen grammatischen Kategorien des Satzes (Realis) und der Nominalphrase (Definitheit, Spezifizität) im Hinblick auf den Status ihrer Referenten in der Diskurswelt, und überlegen anschliessend die ontologische Signifikanz der linguistischen Fakten. Unser Zugang unterscheidet sich in drei wichtigen Hinsichten von vorliegenden Arbeiten. Wir bieten erstens eine Erklärung für die symmetrischen und anti-symmetrischen (invers symmetrischen) Beziehungen, die zwischen Realis (bzw. Irrealis) und Definitheit (bzw. Indefinitheit) bestehen. Zweitens zeigen wir, dass keine Erklärung dieser Beziehungen ohne den Einbezug der grammatischen Kategorie der Spezifizität auskommen kann. Schliesslich untersuchen wir, in welchem Mass die inferentiellen Aspekte der linguistischen Symmetrien und Anti-Symmetrien ontologisch relevant sind, welche Schwierigkeiten sie für das ontologische Standardverständnis von Possibilia aufwerfen, und zeigen, dass eine Ontologie, die mit dynamischen und unbestimmt lokalisierten Individuen verfährt, den linguistischen Daten offenbar besser gerecht wird

Aquinas and the realist dispute in science an Aristotelio-Thomistic contribution to current discussions in language, logic and science

Part I is entirely devoted to current issues in the philosophy of language, logic and science. The burden of the Introduction is to familiarise ourselves with the strengths and weaknesses of scientific realism and scientific anti-realism, and to show that a synthesis of realist and anti-realist tendencies is desirable. Chapters Two and Three deal with a challenge stemming from semantic anti-realists concerning the proper understanding of the nature of truth. The remainder of Part I is devoted to the problem of demarcation. In Chapter 6, which deals with Quine's thesis concerning the indeterminacy of radical translation, I offer a method of distinguishing areas of discourse capable of bearing a realist interpretation from those demanding treatment along anti-realistic lines. Part II beings our study of Aquinas' philosophy of science. Aquinas is presented as offering an intellectual system consistent with conclusions drawn in Part I. Moreover, his attempt to make theology a science on the Aristotelian model is seen to be analogous to our attempt to reconcile realist and anti-realist tendencies in the realist dispute in science

On the Role of Mathematics in Scientific Representation

In this dissertation, I consider from a philosophical perspective three related questions concerning the contribution of mathematics to scientific representation. In answering these questions, I propose and defend Carnapian frameworks for examination into the nature and role of mathematics in science. The first research question concerns the varied ways in which mathematics contributes to scientific representation. In response, I consider in Chapter 2 two recent philosophical proposals claiming to account for the explanatory role of mathematics in science, by Philip Kitcher, and Otavio Bueno and Mark Colyvan. My novel and detailed critique of these accounts shows that they are too limited to encompass the diverse roles of mathematics in science in historical and contemporary scenarios. The conclusion is that any such philosophical account should aim to faithfully capture the structure of our theories and their use in applied contexts. This insight prompts the second question guiding this dissertation that I consider in Chapter 3, regarding a viable philosophical account of the role of mathematics in scientific theories. I respond by proposing a modified form of the reconstructive frameworks for philosophical analysis developed by Rudolf Carnap for theoretical entities. I propose three amendments to Carnap’s account: i) a semantic view for the representation of theories, ii) a careful consideration of instances of the use of theory in representing target systems, and iii) consideration of the practical complexity of relating theory to experimental data. The final research question for this dissertation asks what, if anything, we can legitimately conclude about the nature of theoretical entities invoked by a theory in light of its success in representing phenomena. In the backdrop of the Carnapian frameworks proposed in Chapter 3, I argue that contemporary ontological debates in the philosophy of science are largely premised on an acceptance of Willard Quine’s epistemological outlook on the world and a dismissal of Carnap’s approach, which can be used to offer a satisfactory deflationary resolution. This is in the service of my contention that a Carnapian attitude to central issues in the philosophy of science is decidedly preferable to the route championed by Quine
