Abstract: Existing relevant literature regarding approaches to context formalisation is analysed in search of a
characterisation that explains the links - suggested by knowledge theory of the firm - between knowledge integration
capability and common knowledge types. The ontological and the syntactic-semantic-pragmatic continuum approaches
reveal an extensive description of context, which contributes to the understanding of the knowledge integration process,
and to an eventual operationalisation of common knowledge types. This theoretical development opens possibilities for
the elaboration of prescriptive models that support the integration of knowledge during routine operations of the

Common knowledge, here, One relevant proposition of the knowledge-based accepting these Deweyan pragmatic approaches, theory of the firm is that the ability of an is the kind of knowledge that makes members of organisation to integrate existing knowledge the organisation communicate well, avoid builds up its competitive advantage. The capacity misunderstandings, and be able to solve business to integrate existing knowledge, not the problems together. knowledge itself, is emphasised here (Grant, 1996). Another theorist, Schendel (1996), Grant (1996) goes further, he identifies different proposes that developing new organisational types of common knowledge and argues for a knowledge creates competitive advantage. With a positive relationship between the level and different vocabulary, but referring to same sophistication of common knowledge types - concepts of organisational knowledge, March common language, shared meaning, and (1991) and Spender (1992) refer to "knowledge recognition of individual knowledge domains - and exploitation" as the application of existing the efficiency of the knowledge integration knowledge to deliver goods and services and to process, In spite of Grant's convincing arguments "knowledge exploration" as the generation of new it is problematic to understand and corroborate knowledge. According to all of these theorists, such relationships given the broad scope of the there is a consensus that knowledge is a key independent variables: common language, shared component of organisational capability, whether in meaning and recognition of individual knowledge the exploration or exploitation approach.

The postulate that integration of have not been proposed nor tested to support or existing knowledge to deliver goods and services not the theory. This paper looks into existing in organisations relies upon common knowledge approaches to context for the understanding of for their undertakings is voiced by Grant (1996).

Grant adds that common knowledge is adequate explanation. Common knowledge is constituted by those elements of knowledge that common in regards to what is widely shared are common to the members of an organisation; among members of a group, community or namely, the intersection of their knowledge sets organisation: their context, their environment.

So, in advocating for an approach proposals for each model are described and for understanding the knowledge integration critically evaluated from the common knowledge process in organisations it is necessary to type perspective (see Table 1). understand the domain to which common knowledge types - common language, shared Key-Value Model, (Schilit et al, 1994) allows a meaning, and recognition of individual knowledge basic representation of context.

This approach separates The Webster's English Dictionary tell us that context schema from its content; however new context is a) "the parts of a discourse that contextual relationships are complex to surround a word or passage and can throw light incorporate (it asks for markup language on its meaning", and b) "the interrelated conditions in which something exists or occurs". It is acceptable to conclude that these acceptations of Object Oriented Model (Schmidt et al, 1999) context relate to narratives, situations, and events, exposes the properties – names and values – of a their relations to its surroundings and the context and relationships among properties – thru possibility of inferring meanings from them.

motivation for studying contexts in artificial intelligence is to approach the problem of It is necessary at this point to look into existing generality brought by McCarthy (1987). This approaches to context in order to reveal how problem is exemplified by McCarthy through a context - the domain to which common knowledge system that advise physicians on treating bacterial is common - characterises common language, infections of the blood and meningitis; system shared meanings and recognition of individual which has embedded rules for recommending two knowledge domains. Context is a concept that has weeks of tetracycline treatment and nothing else called the attention of many disciplines - to a patient case that has cholera vibrio in his philosophy, history, psychology, cognitive science, intestines. These rules resulted in a case where linguistics, information science, organisational patient would die long before the bacteria are sciences, artificial intelligence - and there is even gone due to the diarrhoea. The traditional an interdisciplinary conference dedicated to the approach to correct this flaw would be to add a modelling of context.

In summary, the critical evaluation of the approaches from the common knowledge type At first glance, contextual graph could be thought perspective, reveals that: a) Key-Value Model as a notation to draw incident workflows, but its capacity is limited to share an inventory of terms proposed framework, based on focal and about situations or events without meanings subsidiary knowledge (Polanyi, 1962) does associated to them; b) Markup Schema Model describe a knowledge externalisation model that separates context structure form its content and looks for customary incident handling thru the allows sharing of a friendlier common lexicon thru characterisation of context and embedded self a pre-established context model; c) Object explanation.

Finally, Ontology model three common knowledge types but dealing with (Otzturk and Aamodt, 1997; Strang et al, 2003) is the context structure and content ask for a not an information systems approach to context very common knowledge language for formalisation.

The reviewed approaches to context These knowledge structures, proposed as formalisation offer different levels of taxonomies, have differences within in their characterisation to common knowledge types; composition, however general consensus in some however the ontological approach provides the characteristics of the taxonomy of real objects most descriptive capacity and consistent scope exists (Chandrasekaran et al, 1999): 1) there are given its structure (guidelines for context objects in the world, 2) objects have properties taxonomies) and context content (procedures of that can take values, 3) objects can exist in various relations with each other, 4) properties and relations can change over time, 5) there are 4.

The exploration approach. Carlile (2004) recalls transferring capability asks for the development of Shannon and Weaver (1949) seminal work on common lexicon, it deals with the syntactic issues; information theory, which describes the three the translation capability takes care of semantic levels of communication complexity.

Here, I am ready to accept communication. Then, they identify the process by Carlile's knowledge exploration framework and at which symbols actually get meaning as the the same time I argue for a search of a knowledge semantic level; and finally, they consider the exploitation (integration) framework linked to an desired effect of a particular message on a understanding of context as the boundary object.
Choosing to follow this theorising approach – the relations to information, and states that knowledge data-information-knowledge continuum – is not is instrumental; but his definition of data does not fortuitous; it involves the need to describe tell us much. Davenport and Prusak (1998: 2) domains and boundaries of common knowledge in posit that "data is a set of discrete, objective facts doing so it is necessary to consider the existing about events" and that "Unlike data information explanations regarding this continuum. Ackoff has meaning" (1988: 4), and describe knowledge (1989) defines data as "raw … it simply exists and as "a fluid mix of framed experience, values, has no significance beyond its existence … it can contextual information, and expert insight that exist in any form, usable or not … it does not have provides a framework for evaluating and meaning of itself" and posits that information is incorporating new experiences and information. It "data that has been given meaning by way of originates and is applied in the minds of knowers" relational connection . meaning can be useful, (1988: 5). Davenport and Prusak suggest human but does not have to be", and that knowledge is involvement and relationships among data to the application of data and information.

personal level they describe knowledge as an the cyclic aspect of the continuum and show that individual capability to capture more information. the outcomes of information and knowledge In a way, they describe knowledge as a extraction depend on the effectiveness of human complicated, and not very clear, mixture of involvement. Analysing the assessments of this processes that incorporates contextual continuum, it can be argued that its description information; but still data is not yet well described. accomplishes the identification some basic Davenport and Prusak also posit that knowledge categories of data: items and events, which can "In organisations, often becomes embedded not be related to the interrogative primitives only in documents or repositories but also in "what/who" and "when/where" and that perception organisational routines, processes, practices and is the type of human involvement linked to data. norms" (1988: 5). The position here is that Boisot and Canals (2004) are explicit about knowledge is personal and that Davenport and perception when they posit that perceptual filters Prusak are confusing knowledge with guide the senses to certain types of stimuli and representations of data and information. only stimuli passing through this filter get registered as data. Bell (1999) has a more integrated description of this continuum. He states that data is an ordered The issue of perception involves a neural sequence of given items and events, that processing that takes place between the reception information is a context-based arrangement of of a stimulus and its sensing as data by an items and their relations, and that knowledge is individual (Kuhn, 1974). Appealing to Shannon the judgment of the significance of events and and Weaver (1949), it can be added that data is items which comes from a particular context registered using an agreed established symbolic and/or theory. In the case of Bell's knowledge repertoire and syntactic rules – alphabet, definition it is revealing that a judgement of the vocabulary and the language syntax rules (Boisot significance of information can be based on and Canals, 2004). So data is conditioned by context and not only on theory. I will come back to each individual's perceptual filters and at the this issue later on. However, it is the work of same time it is referenced by means of an agreed Tsoukas and Vladimirou (2001) that stresses the shared language – an inter-subjective objectivity ideas behind this continuum. In their research (Popper, 1959). But, where does this agreed case at a customer care department at Greece's shared repertory come from? Polanyi (1966) leading telephone provider, the personnel at the argues that our knowledge of the things denoted customer care department were exposed in their by words will have been largely acquired by work to a lot of discrete items (names, addresses experience – mental or physical; so these words and phone numbers) and business rules (if incorporated in discourses, or associated to <problem> then <check this or that>) where their situations or events were previous experiences in use required a certain level of judgment; departing the chain of perceptual filters and it's sensing. The from here and by means of experience, operators extension of the use of language when discovered from verbal hints that they were referencing data is mnemonic and syntactic, that dealing with an unhappy or perplexed customer is, we attach a name to each datum and use it and acted according to the circumstances, following syntax rules, but in order to name data a adapting the business rules to the context of their certain level of human involvement has to be conversations. This case reveals that the level of applied (Tsoukas and Vladimirou, 2001), we need human involvement (Tsoukas and Vladimirou, to discriminate between "this" and "that" (Dewey, 2001) – identifying phone numbers, selecting 1934).

In terms of perceived context, it the challenge to elaborate on conceptual requires a) the identification of organisational specificity that allows the understanding and stakeholders' roles and b) the identification of a formalisation of an approach to common categorised knowledge domain; 4) integration of knowledge types that contributes to its eventual knowledge in products and services is a operationalisation. In this endeavour, it is pragmatic issue mainly assisted by contextual necessary to understand common knowledge and knowledge. The ontological context continuum their types, but in particular, it is essential to approach to common knowledge does not only achieve a characterisation of the domain in configures a proxy to Grant's (1996) knowledge regards to which "common knowledge" is integration process – the case of the knowledge common. This domain was identified as the exploitation approach; but also it complements organisational context and found that context Carlile's (2004) integrative framework for definition has been admitted as an obvious issue managing knowledge across boundaries when but without adequate explanation. Existing innovation is desired - the case of the knowledge relevant literature reviews regarding approaches exploration approach. Finally, it opens possibilities to context formalisation were considered in order for the elaboration of prescriptive models that to compare, analyse and reclassify the context support the integration of knowledge during approaches. This effort was a search for the routine operations of the organisation. References

Perosino G.C., 2012. Scienze della Terra (cap. 2 - modulo V). CREST (To). 2 - ELEMENTI DI PALEOECOLOGIA 2.1 - Definizione di ecologia Il termine ecologia deriva dal greco oikos che significa "casa" o "posto per vivere". L'ecologia è lo studio degli organismi nella loro casa, ma viene anche definita come lo studio delle relazioni fra organismi o gruppi di organismi ed il loro ambiente e tenta di definire l'insieme di innumerevoli fenomeni e relazioni che caratterizzano sistemi molto complessi. Nello stagno, per esempio, avvengono processi di sedimentazione che, nel tempo, portano al suo riempimento. I materiali che si depositano sul fondo hanno caratteri che dipendono da quelli fisici e chimici delle acque e soprattutto dagli apporti di detriti minerali ed organici dagli ambienti circostanti. La presenza di organismi, solitamente rigogliosa, costituisce l'aspetto più rilevante ed arricchisce i sedimenti di sostanza organica. Ma la presenza di quegli organismi, sia come quantità, sia come composizione di specie, dipende dai caratteri fisici e chimici delle acque e questi a loro volta dipendono anche dal clima della regione nella quale si trova quello stagno. Il clima a sua volta influenza la composizione della vegetazione che si trova intorno al bacino, nell'ambito della quale trovano rifugio animali che si nutrono di prede che trovano nell'acqua. È un insieme di relazioni il cui elenco sembra senza fine, ma che, man mano che vengono studiate, consentono di ottenere un quadro generale sempre più attendibile di quell'ambiente.
