About this topic
Summary Two-dimensional semantic theories postulate two "dimensions" of meaning or content, each understood in terms of possible worlds.  The second dimension is typically depends on the external referents of expressions involved, while the first dimension captures the way that reference depends on the world.  There are many different two-dimensional frameworks.  David Kaplan develops a framework involving "character" and "content" to understand the meaning of indexicals and demonstratives.  Robert Stalnaker develops a framework involving "diagonal propositions" and "propositions expressed" to understand assertion and its relation to context.  David Chalmers and Frank Jackson develop frameworks involving "primary intensions" and "secondary intensions" (or "A-" and "C-intensions") to understand the relation between apriority and necessity and also to understand an internal Fregean dimension of content. 
Key works The origins of 2D semantics lie in work on 2D modal logic by  Kamp 1968 and Vlach 1973.  Various 2D analyses of meaning and content are given by Kaplan 1989, Stalnaker 1978, Evans 1979, Davies & Humberstone 1980, Chalmers 1996, and Jackson 1998Soames 2005 is a book-length critique of many different versions.  Numerous papers are collected in Garcia-Carpintero & Macia 2006.
Introductions Chalmers 2006 and Schroeter 2010 give overviews of various different two-dimensional semantic frameworks, along with their motivations and objections to them.

    Indicative and Subjunctive Conditionals.Brian Weatherson - 2001 - Philosophical Quarterly 51 (203):200-216.
    This paper presents a new theory of the truth conditions for indicative conditionals. The theory allows us to give a fairly unified account of the semantics for indicative and subjunctive conditionals, though there remains a distinction between the two classes. Put simply, the idea behind the theory is that the distinction between the indicative and the subjunctive parallels the distinction between the necessary and the a priori. Since that distinction is best understood formally using the resources of two-dimensional modal logic, (...)

    One well known problem regarding quantifiers, in particular the 1storder quantifiers, is connected with their syntactic categories and denotations. The unsatisfactory efforts to establish the syntactic and ontological categories of quantifiers in formalized first-order languages can be solved by means of the so called principle of categorial compatibility formulated by Roman Suszko, referring to some innovative ideas of Gottlob Frege and visible in syntactic and semantic compatibility of language expressions. In the paper the principle is introduced for categorial languages generated (...)

    In the Mood.Kai Frederick Wehmeier - 2004 - Journal of Philosophical Logic 33 (6):607-630.
    The purpose of the present paper is to challenge some received assumptions about the logical analysis of modal English, and to show that these assumptions are crucial to certain debates in current philosophy of language. Specifically, I will argue that the standard analysis in terms of quantified modal logic mistakenly fudges important grammatical distinctions, and that the validity of Kripke's modal argument against description theories of proper names crucially depends on ensuing equivocations.

    Abstract: In recent years two-dimensional semantics has become one of the most serious alternatives to Millianism for the proper interpretation of modal discourse. It has origins in the works of a diverse group of philosophers, and it has proven popular as an interpretation of both language and thought. It has probably received most of its attention, however, because of its use by David Chalmers in his arguments against materialism. It is this more metaphysical application of two-dimensionalism that is the concern (...)

    If-Clauses as Postsemantic Context-Shifters.Benj Hellie - manuscript
    A mainstay assumption in natural-language semantics is that \emph{if}-clauses bind indexical argument-places in \emph{then}-clauses. Unfortunately, recent work (compare \citealt{santorio12}) suggests that \emph{if}-clauses can somehow act to `shift the context'. On the framework of Kaplan's `Demonstratives' \citep{kaplan77}, that would be `monstrous' and somehow impossible `in English'. The superseding framework of Lewis's `Index, context, and content' \citep{lewis80icc} instead maintains that an indexical argument-place is just one that is bindable (compare~\citealt[ch.~1]{stalnaker14}), but maintains that these are rare---whereas the lesson of recent work is that (...)

    We present a sound and complete Fitch-style natural deduction system for an S5 modal logic containing an actuality operator, a diagonal necessity operator, and a diagonal possibility operator. The logic is two-dimensional, where we evaluate sentences with respect to both an actual world (first dimension) and a world of evaluation (second dimension). The diagonal necessity operator behaves as a quantifier over every point on the diagonal between actual worlds and worlds of evaluation, while the diagonal possibility quantifies over some point (...)

The most compelling objections to E2D are that, for one or other reason, the requisite intensions are not accessible from the armchair (see, e.g., Wilson 1982, Melnyk 2008). As we substantiate (...)

We newly propose that languages that select the subjunctive with epistemic predicates allow us to see a systematic polysemy between what we call an expressive-`belief' (featuring only a doxastic dimension) and an inquisitive-`belief' (featuring both a doxastic and an epistemic dimension conveying doxastic certainty (in the assertion) and epistemic uncertainty (in the presupposition)).

    This paper argues for a particular view about in what metaphysical equivalence consists: namely, that any two metaphysical theories are metaphysically equivalent if and only if those theories are strongly hyperintensionally equivalent. It is consistent with this characterisation that said theories are weakly hyperintensionally distinct, thus affording us the resources to model the content of propositional attitudes directed towards metaphysically equivalent theories in such a way that non-ideal agents can bear different propositional attitudes towards metaphysically equivalent theories.

    Standard approaches to possible-world semantics allow us to define necessity and logical truth, but analyticity is considerably more difficult to account for. The source of this difficulty lies in the received model-theoretical conception of a language interpretation. In intuitive terms, analyticity amounts to truth in virtue of meaning alone, i.e. solely in virtue of the interpretation of linguistic expressions. In other words, an analytic sentence should remain true under all variations of ‘extralinguistic reality’ as long as the interpretation is kept (...)

    Many authors have noted that there are types of English modal sentences cannot be formalized in the language of basic first-order modal logic. Some widely discussed examples include “There could have been things other than there actually are” and “Everyone who is actually rich could have been poor.” In response to this lack of expressive power, many authors have discussed extensions of first-order modal logic with two-dimensional operators. But claims about the relative expressive power of these extensions are often justified (...)

    According to the modal account of propositional apriority, a proposition is a priori if it is possible to know it with a priori justification. Assuming that modal truths are necessarily true and that there are contingent a priori truths, this account has the undesirable consequence that a proposition can be a priori in a world in which it is false. Epistemic two-dimensionalism faces the same problem, since on its standard interpretation, it also entails that a priori propositions are necessarily a (...)

    Many expressions intuitively have different epistemic and modal profiles. For example, co-referring proper names are substitutable salva veritate in modal contexts but not in belief-contexts. Two-dimensional semantics, according to which terms have both a so-called primary and a secondary intension, is a framework that promises to accommodate and explain these diverging intuitions. The framework can be applied to indexicals, proper names or predicates. Graeme Forbes argues that the two-dimensional semantics of David Chalmers fails to account for so-called nested contexts.

    It is a core commitment of Epistemic Two-Dimensionalism that an utterance is 1-necessary iff it is a priori. But Jeff Speaks's Argument from Misclassification proves that, on a natural interpretation, E2D assigns necessary 1-intensions to many utterances that speakers deem a posteriori. Given that 1-intensions are meant to formalize a speaker's own understanding of the words she utters, this proof raises serious difficulties for E2D.

Contrary to received views, it argues further that epistemological truth theories operate on Lewisian possible worlds and ontological truth theories on Wittgensteinian possible worlds and that both are mediated by the so-called epistemic-ontic map the further specification of which is of utmost philosophical importance.
