Tracing Metaphors in Time through Self-Distance in Vector Spaces
نویسندگان
چکیده
English. From a diachronic corpus of Italian, we build consecutive vector spaces in time and use them to compare a term’s cosine similarity to itself in different time spans. We assume that a drop in similarity might be related to the emergence of a metaphorical sense at a given time. Similarity-based observations are matched to the actual year when a figurative meaning was documented in a reference dictionary and through manual inspection of corpus occurrences. Italiano. Nel presente esperimento costruiamo spazi vettoriali progressivi nel tempo su un corpus diacronico dell’italiano e calcoliamo la distanza di alcuni termini rispetto a loro stessi in differenti periodi. L’ipotesi è che un calo di similitudine possa essere indicativo dell’acquisizione di un significato metaforico. Tale ipotesi è valutata attraverso una risorsa lessicografica esterna e l’annotazione manuale dei contesti dei termini nel corpus.

Some properties of continuous linear operators in topological vector PN-spaces
The notion of a probabilistic metric space corresponds to thesituations when we do not know exactly the distance. Probabilistic Metric space was introduced by Karl Menger. Alsina, Schweizer and Sklar gave a general definition of probabilistic normed space based on the definition of Menger [1]. In this note we study the PN spaces which are topological vector spaces and the open mapping an...
متن کاملThe Time Adaptive Self Organizing Map for Distribution Estimation
The feature map represented by the set of weight vectors of the basic SOM (Self-Organizing Map) provides a good approximation to the input space from which the sample vectors come. But the timedecreasing learning rate and neighborhood function of the basic SOM algorithm reduce its capability to adapt weights for a varied environment. In dealing with non-stationary input distributions and changi...
متن کاملError bounds in approximating n-time differentiable functions of self-adjoint operators in Hilbert spaces via a Taylor's type expansion
On utilizing the spectral representation of selfadjoint operators in Hilbert spaces, some error bounds in approximating $n$-time differentiable functions of selfadjoint operators in Hilbert Spaces via a Taylor's type expansion are given.
متن کاملCommon fixed points for a pair of mappings in $b$-Metric spaces via digraphs and altering distance functions
In this paper, we discuss the existence and uniqueness of points of coincidence and common fixed points for a pair of self-mappings satisfying some generalized contractive type conditions in $b$-metric spaces endowed with graphs and altering distance functions. Finally, some examples are provided to justify the validity of our results.
متن کاملVelocity Modeling in a Vertical Transversely Isotropic Medium Using Zelt Method
In the present paper, the Zelt algorithm has been extended for ray tracing through an anisotropic model. In anisotropic media, the direction of the propagated energy generally differs from that of the plane-wave propagation. This makes velocity values to be varied in different directions. Therefore, velocity modeling in such media is completely different from that in an isotropic media. The vel...
