	Ketamine Psychedelic Therapy (KPT): Review of the Results of a 10-Year Study

		Semantic space of the personality (built on the basis of multidimentional assessments of elements with constructs) shows semantic interrelationships and interconnections between elements and/or constructs of repertory grid.

	IBM Research - SLAM - Semantic Learning and Analysis of Multimedia
		To enable the efficient and scalable modeling of semantic concepts in high-dimensional low-level media feature spaces, we investigate the application of machine learning algorithms that provide us with generic trainable procedures to model the semantic concepts.
		Once the semantic space spanned by a lexicon of several hundred concepts is constructed using the models for these semantic concepts, further analysis and mining at a semantic level is feasible.
		A related research challenge is to expand highly semantic queries to the lexicon that is modeled using feature-vector-based modeling.

		Iíd like to see Google provide the canonical profile document for this usage, because it represents a new semantic category: search engine instructions.
		I donít have a problem with that per se, since the intent of this link type is that it extends the weak protection afforded by robots.txt for the document into a stronger protection inside the content itself.

		Event spaces, which come about from semantics of concurrency, provide another semantic framework for linear logic [23] A mathematical setting for dynamic aspects of cut elimination is provided by proof nets [10, 9] and in a deeper sense by Girard s geometry of interaction [11, 12, 8, 24, 1, 13,....
		Both settings, in addition to coherent domains, 3 are now understood to yield mathematical models for linear logic proofs, more precisely, for the relation t is a linear logic proof of a formula A [26, 88, 18, 19] Other versions of game semantics are given by Abramsky and Jagadeesan [2]....
		A Chu Mackey space, or just Chu space, over a set K is simply a rectangular array over K, that is, a function from A Theta X to K where the sets A and X index the rows and columns respectively.

	Prepared as an Invited Keynote Address: Culture of Peace - Intersymp 97
		Central is the idea to use space not only as a real world platform to position and share objects, but also to bridge and follow meaning into embodied context and semantic spaces which form an organic or holistic world- view.
		When we accept that cognitive spaces are vehicles or open rooms, ideally suited to carry meaning across domains and cultures, we can think about the dimensions: width, height, and depth.
		The answer to these challenges was to visualize spaces by realizing them physically and literally as abstract or cognitive spaces, by building a `Situation or Operation Space '.

		Chu spaces as a semantic bridge between linear logic and mathematics
		Event spaces resemble finite-dimensional vector spaces in distinguishing tensor product from direct product and in being isomorphic to their double dual, but differ from them in distinguishing direct product from direct sum and tensor product from tensor sum.
		We prove full completeness for a fragment of the linear logic of the self-dual monoidal category of Chu spaces over 2, namely that the proofs between semisimple (conjunctive normal form) formulas of multiplicative linear logic without constants having two occurrences of each variable are in bijection with the dinatural transformations between the corresponding functors.

	Research
		Typically, pairwise similarity judgments are used to infer these multidimensional representations but I have shown how to extend this framework to learn semantic spaces for words based on word association (Steyvers, Shiffrin, and Nelson, 2004) and perceptual representations for faces based on physical features as well as similarity ratings (Steyvers and Busey, 2000).
		This pattern of connectivity is difficult to explain on the basis of Euclidian spaces.

	Semantics for Second Order Communication
		This space includes the semantic-state, semantic-store, semantic-communication and semantic-action spaces.
		The denotational semantics for this construct employs a space that is defined as the solution of a recursive equation.
		The basic components of the imperative language in which the second order communication is to be implemented are: a set of variables (v), a set of expressions (e), a set of boolean expressions (b), a set of channels (c) and a set of statement variables (x).

	The Necessity for Information Space Mapping for Information Retrieval on the Semantic Web
		For this long-term goal to be realized, information spaces of IR systems would need to be tightly coupled to the cognitive spaces of their individual users.
		The pertinence to IR systems' information spaces is that, as for human communication, an utterance or document cannot be effectively understood or exchanged without some shared information space.
		Rule-based techniques will enable mapping between the information spaces of different documents or document sets based on knowledge about those documents or inherited from other documents.

	Moving Hands Music Magazine - Delerium, Poem
		Delerium have ever since the shocking release of "Semantic Spaces" been developing a more commercial sound that completely differs from the dark atmosphere of the old days.
		Delerium's current "Dance Club" phase began with two more outstanding must-have productions, "Semantic Spaces" and "Karma".
		The biggest change would be the more frequent use of acoustic guitars but also the number of instruments used, and the many guest appearances.

	Dawson Margin Notes On Smith Vol 3 Intro
		Smith was one of the major proponents of the set-theoretic approach, which does not require the metric assumptions of similarity spaces.
		Smith was one of the leading figures in the major cognitive psychology debate of the 1970s, feature matching models of semantic memory vs semantic network models.
		The axiom of symmetry is undermined by the finding that an unfamiliar category is judged more similar to a familiar or prominent category than the other way around," Smith's approach is to move away from geometric spaces because of these difficulties.

	associative memory
		Now we can specify an associative memory between the two vector spaces, one being a theme space and the other being a semantic space.
		Associative memories between theme space and semantic space
		Our strategy is to utilize multiple types of representations and then to create an associative memory between the representational spaces.

	Delerium - Karma
		Delerium's latest, Karma, is pretty much a direct follow-on from 1994's Semantic Spaces, and offers the same mix of club-friendly rhythms, chants and female vocals.
		It's a gentle lead-in for the album, as it's one of the more Semantic Spaces-like tracks here.
		This track was (deservedly, I feel) the first single from the album, and was released at roughly the same time as the album, back in April.

	Shannon and information theory
		Shannon also considers more elaborate probabilistic models of spaces of possible messages by considering instead probability spaces defined on diagrams (pairs of successive letters), so that for example the probability of the occurrence of "a" can depend on the previous symbol, but with diagrams like "ab" still being chosen independently with the appropriate frequency.
		These semantic aspects of communication are irrelevant to the engineering problem", he is stressing that only the statistical structure of messages, and the -statistical- correlation of the behavior of dynamical systems, is relevant in his theory.
		Here we have "entropies" which still measure "the variety of alternatives" associated with some "choice", but now the alternatives are alternative -motions- of some set of points in X under the given action, and the "choice" of one of these alternative motions does not a priori involve any notion of probability.

	PRG Technical Report TR-6-00
		A Galois connection is a `natural' way of relating two partially-ordered spaces (for example semantic models of different expressive power).
		This letter shows a published claim, `two partially-ordered spaces related by a Galois embedding in each direction are isomorphic', to be false in general but true in the finite case.
		The most common form of Galois connection, which reflects one model being finer than the other, is that of a Galois embedding.

	Sherman Wilcox - Research
		According to this model, iconicity is a property of the geometry of conceptual spaces in which both phonological and semantic structures reside: iconicity is a characteristic of this situations in which the phonological pole of a symbolic unit resides in close proximity in conceptual space to the semantic pole.
		For many years iconicity in signed languages was regarded as a feature which detracted from their status as fully developed human languages.
		In a series of studies I have been developing a model of iconicity based on cognitive linguistics which recognizes its pervasiveness both in the lexicon and the grammar.

	Re: Linear logic semantics (Barwise) (353 lines)
		Both the coherent spaces and the phase spaces are discussed in Girard's TCS paper on linear logic.
		Another semantic aspect of linear logic that should be emphasized is in Girard's "Geometry of Interaction" in Logic Colloquium '88 (North-Holland yellow series), in Danos' exposition of geometry of interaction (in French) in Gazette Math.
		A logician might identify this duality with word-object duality, the Galois connection between theories and classes of structures, with position naturally identified with word and momentum with object.) This symmetry of observation means that not all observers can be perfect.

	OSU Department of Computer Science and Engineering Presents
		For disambiguation of the semantic role structure of verbs, I describe a model that captures regularities of the label space and incorporates the knowledge that the semantic frame of a verb is a joint structure with strong dependencies between arguments.
		I advance the state of the art in several domains by (i) choosing representations that encode domain knowledge more effectively and (ii) developing machine learning algorithms that deal with the specific properties of linguistic disambiguation tasks - sparsity of training data and large, structured spaces of hidden labels.
		For syntactic disambiguation, I present a novel representation of parse trees that connects the words of the sentence with the hidden syntactic structure in a direct way and leads to natural definition of tree kernels via convolution of string kernels.

	Curriculum Vitae
		This book is an introduction to geometric models including graphs, hierarchies, metric spaces, vector spaces, lattices and logics, describing the way these have been used to represent and classify concepts, especially in natural language.
		The reader is introduced to modern applications including semantic networks, search engines, and methods for automatic concept-learning and disambiguation.
		The story of these ideas is traced through the footsteps of great scientists including Aristotle, Euclid, Descartes, Hamilton, Grassmann, Darwin, Boole, Birkhoff and von Neumann.

	Delerium: album reviews and ratings
		Capitalising on the success of Semantic Spaces, the duo embarked on a much more ambitious project, their 1997 release Karma, where they worked with Kristy Thirsk, Sarah McLachlan, Jacqui Hunt, and sampled extracts from Dead Can Dance and Lisa Gerrard songs.
		Karma was the last joined effort between Leeb and Fulber, as the latter decided to leave the formation and concentrate on his own work.
		"This is a drastic departure from all the previous works of Bill Leeb and Rhys Fulber, although it has some references to older material, like older Delerium and some Intermix, though it has very little to do with their main project Front Line Assembly.

	Synaesthesia -
		Those who enjoyed any of those releases - Semantic Spaces or later Delerium, the previous Synaesthesia disc, or the most recent Intermix album - shouldn't be disappointed by the contents of this disc.
		The prolific Bill Leeb and Rhys Fulber strike again.
		Oh, no, sorry, my mistake, I forgot - this is Synaesthesia, so all credit goes once again to the mysterious R. Deckard, with the Delerium duo responsible only for production, engineering and mixing.

	Delerium: Chimera - PopMatters Music Review
		Mention must also be made of the album's two instrumentals, on which the hand of Rhys Fulber is most evident but which also, it must be said, sound like sleepy retreads of his and Leeb's Semantic Spaces and Karma heyday.
		Fulber has returned to the Delerium fold for Chimera, but he brings little of the Conjure One magic with him in what seems to have been a limited role -- he shares songwriting credit on just six of the album's 13 tracks.
		It must be weird when your obscure 10-year-old side project suddenly vaults over your main gig and into the international spotlight, but that's pretty much exactly what happened to Bill Leeb and Rhys Fulber when they recorded a little tune with fellow Canadian Sarah McLachlan called "Silence" for their ninth studio album, Karma, in 1997.

	Mindphaser 3.0
		The third album "Future Primitives" (1994) surprised with a totally different sound again, and can be best described as the male version of Deleriums "Semantic Spaces", as it was far more ambient than the previous Intermix material and featured monk and tribal chant samples in many places.
		Intermix provided an outlet for a more dance oriented sound for the duo at first.
		A single "Dream On" came out at the same time, its tracks were then re-released on the second album "Phaze Two" (1993), which had a far more technoish and dancey sound than the debut, and was promoted by 2 videoclips by Rod Chong.
